AIMS : This randomized controlled trial aimed to evaluate the benefits and clinical outcomes of piezocision, which is a minimally invasive approach to corticotomy that is used in orthodontic treatments. MATERIALS AND METHODS : Twenty-four adult patients presenting with mild overcrowdings were randomly allocated to either a control group that was treated with conventional orthodontics or a test group that received piezo-assisted orthodontics. The piezocisions were performed 1 wk week after the placement of the orthodontic appliances. Neither grafting material nor sutures were used. All patients were followed every 2 wk, and archwires were changed only when they were no longer active. The periods required for the completion of the overall orthodontic treatments were calculated, and the periodontal parameters were evaluated at baseline and at the end of the orthodontic treatment. Patient-centered outcomes were assessed with a visual analog scale; analgesic use following the procedures was also recorded. RESULTS : The patient characteristics were similar between the 2 groups. The overall treatment time was significantly reduced by 43% in the piezocision group as compared with the control group. In both groups, periodontal parameters (i.e., recession depth, pocket depth, plaque index, and papilla bleeding index) remained unchanged between the baseline and treatment completion time points. No increase in root resorption was observed in either group. Scars were observed in 50% of the patients in the piezocision group. Analgesic consumption was similar following orthodontic appliance placement and piezocision surgery. Patient satisfaction was significantly better in the piezocision group than in the control group. CONCLUSION : In these conditions, the piezocision technique seemed to be effective in accelerating orthodontic tooth movement. No gingival recessions were observed. The risk of residual scars might limit the indications for piezocision in patients with a high smile line (ClinicalTrials.gov NCT02590835) [less ▲]

AIMS: The primary objective was to assess the occurrence rate of Medication-Related OsteoNecrosis of the Jaw (MRONJ) after dental extraction in patients treated with Anti-Resorptive Drugs (ARD) for OsteoPorosis (OP) or for oncological reasons. The secondary objective was to compare the extraction techniques regarding the occurrence of MRONJ. MATERIALS AND METHODS: A systematic search in PubMed/MEDLINE, EMBASE and LILACS databases was performed. Prospective studies considering human patients treated with ARD and providing information regarding the occurrence of MRONJ after dental extraction were selected. Meta-analysis for incidence of MRONJ at the patient level was performed. The effect of administration route and surgical technique on MRONJ was evaluated. RESULTS: The risk of MRONJ after dental extraction was significantly higher in patients treated with ARD for oncological reasons (3.2%) than in those treated with per os ARD for OP (0.15%) (p<0.0001). Dental extraction performed with adjusted extraction protocols decreased significantly MRONJ development. Potential risk indicators such as concomitant medications and pre-existing osteomyelitis were identified. CONCLUSION: The risk of MRONJ after dental extraction in patients treated with ARD exists, especially in patients treated for oncologic reasons. This risk tends to decrease with adjusted extraction protocols. This article is protected by copyright. All rights reserved. [less ▲]

Abstract AIMS: Over the past decades, the placement of dental implants has become a routine procedure in the oral rehabilitation of fully and partially edentulous patients. However, the number of patients/implants affected by peri-implant diseases is increasing. As there are--in contrast to periodontitis--at present no established and predictable concepts for the treatment of peri-implantitis, primary prevention is of key importance. The management of peri-implant mucositis is considered as a preventive measure for the onset of peri-implantitis. Therefore, the remit of this working group was to assess the prevalence of peri-implant diseases, as well as risks for peri-implant mucositis and to evaluate measures for the management of peri-implant mucositis. METHODS: Discussions were informed by four systematic reviews on the current epidemiology of peri-implant diseases, on potential risks contributing to the development of peri-implant mucositis, and on the effect of patient and of professionally administered measures to manage peri-implant mucositis. This consensus report is based on the outcomes of these systematic reviews and on the expert opinion of the participants. RESULTS: Key findings included: (i) meta-analysis estimated a weighted mean prevalence for peri-implant mucositis of 43% (CI: 32-54%) and for peri-implantitis of 22% (CI: 14-30%); (ii) bleeding on probing is considered as key clinical measure to distinguish between peri-implant health and disease; (iii) lack of regular supportive therapy in patients with peri-implant mucositis was associated with increased risk for onset of peri-implantitis; (iv) whereas plaque accumulation has been established as aetiological factor, smoking was identified as modifiable patient-related and excess cement as local risk indicator for the development of peri-implant mucositis; (v) patient-administered mechanical plaque control (with manual or powered toothbrushes) has been shown to be an effective preventive measure; (vi) professional intervention comprising oral hygiene instructions and mechanical debridement revealed a reduction in clinical signs of inflammation; (vii) adjunctive measures (antiseptics, local and systemic antibiotics, air-abrasive devices) were not found to improve the efficacy of professionally administered plaque removal in reducing clinical signs of inflammation. CONCLUSIONS: Consensus was reached on recommendations for patients with dental implants and oral health care professionals with regard to the efficacy of measures to manage peri-implant mucositis. It was particularly emphasized that implant placement and prosthetic reconstructions need to allow proper personal cleaning, diagnosis by probing and professional plaque removal. [less ▲]

Nous sommes tous bien conscients de la problématique liée au remodelage osseux après extraction dentaire, en particulier dans la zone esthétique. Les conséquences cliniques sont telles que le recours à des techniques de régénération tissulaire est souvent nécéssaire pour la pose de l'implant et pour assurer des résultats esthétiques. Cet article vise à démontrer l'efficacité d'un protocole d'optimisation tissulaire basé sur la préservation du capital osseux et sur l'optimisation des tissus gingivaux lors d'une extraction dentaire dans la zone esthétique. L'objectif de cet article est de suggérer un processus décisionnel en matière de technique chirurgicale, reposant d'une part sur l'examen clinique initial et, d'autre part, sur une excellente compréhension du concept biologique.

Narrow diameter implants (NDIs) are increasingly produced and used in implant dentistry especially since the introduction of new and more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Methods: Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤ 6 mm were treated with one or several NDIs. The surgical protocol was chosen according to the clinical situation: °1 flapless; °2 mini-cervical flap; 3° wide flap; 4° wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates and patient-centered outcomes were evaluated after a follow-up period of 1 year. Results: A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All implants but one reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7 %. The need for GBR was avoided in 60 % of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was -0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition.Conclusion: The use of NDIs to restore partial edentation in sites with limited horizontal bone thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results. [less ▲]

PURPOSE: To evaluate the effectiveness of a bone substitute covered with a resorbable membrane versus open flap debridement for the treatment of periodontal infrabony defects. MATERIALS AND METHODS: Ninety-seven patients with one infrabony defect, which was 3 mm or deeper and at least 2 mm wide were randomly allocated either to grafting with a bone substitute covered with a resorbable barrier (BG group) or open flap debridement (OFD group) according to a parallel group design in five European centres. Blinded outcome measures assessed tooth loss, complications, patient's satisfaction with treatment and aesthetics, changes in probing attachment levels (PAL), probing pocket depths (PPD), gingival recessions (REC), radiographic bone levels (RAD) on standardised periapical radiographs, plaque index (PI) and marginal bleeding index (MBI). RESULTS: 49 patients were randomly allocated to the BG group and 48 to the OFD group. At baseline there were more mobile teeth in the BG group (29 versus 15). One year after treatment two patients dropped out from the BG group and no teeth were lost. Three complications (minor postoperative wound dehiscence) occurred in the BG group versus none in the OFD group, where the difference was not statistically significant. The BG group obtained significantly greater statistical PAL gain (mean difference = -0.8 mm, 95%CI [-1.51; -0.03], P = 0.0428), PPD reduction (mean difference = -1.1 mm, 95%CI [-1.84; -0.19], P = 0.0165) and RAD gain (mean difference = -1.2 mm, 95%CI [-2.0; -0.4], P = 0.0058) compared to the OFD group. No statistically significant differences between the groups were observed for gingival recession, or the patient's satisfaction with the treatment and aesthetics. There were some statistically significant differences between the centres for PAL and PPD with the Italian centres reporting better outcomes. CONCLUSIONS: The use of a bone substitute covered with a resorbable membrane yielded significantly better statistical clinical outcomes than open flap debridement in the treatment of periodontal infrabony defects deeper than 3 mm, with regard to PAL gain, PPD reduction and RAD gain.

Osteoporosis affects millions of elderly patients, and anti-resorptive drugs (ARD) such as bisphosphonates (BP) represent the first-line therapy. Despite the benefits related to the use of these medications, osteonecrosis of the jaw is a significant complication in a subset of patients receiving these drugs. CASE PRESENTATION: This report documents a case of dramatic bisphosphonate-related osteonecrosis associated with periodontitis and dental implant removal in an osteoporotic patient treated with per os bisphosphonates for an uninterrupted period of 15 years. CONCLUSION: The aim of this report was to discuss the administration period of BP in the treatment of osteoporosis, the decision-making and clinical management of severe MRONJ and the indications for dental implant placement in these specific patients.

AIM: The objective of this study was to compare two different periodontal plastic surgery procedures to treat Miller's class I recession: a coronally advanced flap (control group) versus the pouch technique (test group), both of which were associated with connective tissue graft. METHODS: Forty consecutive patients were included, with 20 patients being allocated for each group. The level of recession coverage, the keratinized tissue (KT) quantity, gingival aesthetics (PES) and post-operative outcomes were assessed for a follow-up period of 6 months. RESULTS: After 6 months, both techniques allowed for the excellent mean root coverage of 96.3 ± 12.1% in the control group and of 91.3 ± 17.6% in the test group. Complete root coverage was achieved in 89.5% (17/19) and 79% (15/19) of the recession cases in the control and the test groups respectively. A significant increase in KT height (p = 0.0011) was observed in the test group. A significant improvement in the pink aesthetic score was found in the two groups, but gingival texture displayed significantly better results in the test group (p < 0.0001). No significant difference between the two groups was found in terms of the morbidity outcomes. Pain killer consumption was similar in the two groups and significantly decreased over time. CONCLUSIONS: Both surgical techniques are relevant in treating Miller's class I recession. The pouch technique seems to increase the height of KT better and provides good gingival-related aesthetic outcomes. [less ▲]

BACKGROUND Osteoporosis affects millions of elderly patients. Bisphosphonates represent first-line therapy. Osteonecrosis of the jaws in patients treated with bisphosphonates is mostly associated with intravenous bisphosphonates while the incidence associated with oral bisphosphonates is not significant. AIM This report documents a case of bisphosphonate-related osteonecrosis of the jaw (BRONJ) after dental implant removal in an osteoporotic patient treated with alendronate and risedronate for 15 years. MATERIAL AND METHODS An 83-years-old patient with no significant systemic disease underwent implant removal in the first molar left hemimandible position in 2010 due to a peri-implantitis. The surgical procedure was uneventful thought preventive measures were no taken. In June 2011, the patient was referred to our department with a wide bone sequestration of the left mandibular body. A panoramic radiograph showed an increased bone marrow density with bone sequestration. Since then, the patient underwent several courses of antibiotics and conservative therapy, without relief of symptoms. RESULTS Since 2011, the patient has lost 13 teeth in the mandible and the osteonecrosis has disseminated to the entire jaw and the left mandible condyle. The patient has even lost the left hearing. Resective surgery under general anesthesia is not indicated due to the risk because of the age of the patient. CONCLUSION AND CLINICAL IMPLICATIONS Despite the low risk of BRONJ occurrence after implant surgery in oral N-BP users, the fate of dental implants in these patients remains uncertain. Therefore patients at risk must be given a full explanation of the potential risks of implant failure and BRONJ development. Osteonecrosis of the jaws in association with bisphosphonate therapy is a very serious condition with which all dentists should be familiar. Since the treatment of BRONJ is difficult, prevention is the main goal. When the osteonecrosis begins, it can be very painful to the patient, difficult to treat, and can lead to very deleterious sequelae. [less ▲]

BACKGROUND: The positive effect of leukocyte- and platelet-rich fibrin (L-PRF) on osteogenesis has been widely described in vitro. However, clinical and preclinical studies are very little and controversial in demonstrating a significant beneficial effect of L-PRF in bone regeneration. PURPOSE: The goal of the present study was to compare the potential effect of L-PRF in a standardized model. MATERIALS AND METHODS: A total of 72 hemispheres were implanted on the calvaria of 18 rabbits and filled with three different space fillers: L-PRF, bovine hydroxyapatite (BHA), BHA + L-PRF, and an empty hemisphere was used as control. Six rabbits were sacrificed at three distinct time points: 1 week, 5 weeks, and 12 weeks. Histological and histomorphometrical analyses were carried out. RESULTS: At the early phase of bone regeneration (1 week), from a descriptive analysis, a higher proportion of connective tissue colonized the regeneration chamber in the two groups containing BHA particles. Nevertheless, no statistical differences were found within the four groups in terms of bone quantity and quality at each timepoint (p = .3623). CONCLUSIONS: According to the present study, L-PRF does not seem to provide any additional effect on the kinetics, quality, and quantity of bone in the present model of guided bone regeneration.
