Titanium has been proposed as a mesh material for guided bone regeneration (GBR) since the 1990s. To overcome difficulties in shaping and adapting meshes to the defect, digital techniques were introduced to digitally print meshes capable of fitting the bone perfectly, reproduced through the patient's CT scan. Five patients were included in this case series, and their CBCT data were acquired and sent to the producer of the titanium meshes. 3D regenerative surgery was performed with titanium meshes and a mix of demineralized bovine bone matrix (DBBM) and autogenous bone (1:1 ratio). Radiographic measures were evaluated on paraxial sections of the CBCT through a dedicated software. When possible, regenerated bone samples were obtained at implant insertion. Four out of five regenerated areas healed without local or systemic complications. One mesh was removed after 2 months and 2 weeks due to exposure. The mean vertical bone gain was 4.3 ± 1.5 mm (range: 2.5 to 7 mm). Two histologic samples were obtained. In sample 1, bone tissue area and graft material area were 44.4% and 12.5%, respectively; in sample 2, the same parameters were 15.6% and 16.9%, respectively. [ABSTRACT FROM AUTHOR]

The aim of this retrospective study was to evaluate the performance of implants placed with the All-on-4 technique after a mean time in function of 9 years. A total of 34 patients with 156 implants were selected for this study: 18 patients underwent tooth extraction on the day of implant placement (Group D), and 16 patients were already edentulous (Group E). A periapical radiograph was taken at a mean follow-up of 9 years (range: 5 to 14 years). Success and survival rates and the prevalence of peri-implantitis were calculated. Statistical analysis was used to assess comparisons between groups. After a mean follow-up of 9 years, the cumulative survival rate was 97.4% and the success rate was 77.4%. The difference between the initial and final radiographs resulted in a mean marginal bone loss (MBL) of 1.3 ± 1.06 mm (range: 0.1 to 5.3 mm). No differences were seen between Groups D and E. Peri-implantitis affected 15 implants (9.6%) in 9 patients (26.5%). This study shows that the All-on-4 technique is a reliable treatment method for both edentulous patients and patients requiring tooth extractions, with results maintained over a long follow-up period. The present MBL results are similar to those around implants in other rehabilitation types. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions Key points Plain Language Summary Orthodontic treatment in adults with thin periodontal phenotype presents challenges such as lengthy treatment time and increased risk for gingival recessions. In this case, surgically facilitated orthodontic treatment (SFOT) was proposed to accelerate orthodontic tooth movement while modifying the periodontal phenotype.An orthodontic patient was referred for periodontal evaluation of lower anterior teeth, which presented a thin gingival phenotype and bone dehiscence. SFOT was performed on the mandible using particulate allograft combined with platelet rich fibrin (PRF) and collagen membrane to augment soft and hard tissue, thereby preventing future recessions, while accelerating the treatment times.Six‐month and 3‐year follow‐ups confirmed radiographic bone fill, absence of gingival recession and thick band of keratinized gingiva. SFOT also resulted in a shorter treatment time where desired tooth movements were achieved within 6 months with periodontal stability.SFOT provided clinical benefits by accelerating orthodontic movement, improving periodontal phenotype, preventing the displacement of teeth beyond the alveolar housing and minimizing the risk for development of dehiscences and gingival recessions. Orthodontic movements can create recessions and dehiscence in thin periodontal phenotypes. SFOT can help prevent bone dehiscence and creates a thicker gingival phenotype while accelerating treatment time. Orthodontic movements can create recessions and dehiscence in thin periodontal phenotypes.SFOT can help prevent bone dehiscence and creates a thicker gingival phenotype while accelerating treatment time.Adults who face lengthy orthodontic treatments and have thin gums have risks of gum problems. Surgically facilitated orthodontic treatment (SFOT) can help by speeding up tooth movements and improving gum health and thickness.A patient with thin gums and lack of bone in the lower front teeth was evaluated. The SFOT procedure involved using a bone graft, healing factors, and a collagen membrane to strengthen the gums and bones. This approach aimed to prevent future gum problems and speed up orthodontic treatment.Follow‐ups at 6 months and 3 years after treatment showed good healing of the gums and bones, with no signs of gum recession and healthier, thicker gums. The desired tooth movements were achieved within 6 months, resulting in a shorter treatment time. The patient's gums remained stable throughout this period.SFOT offered significant clinical benefits, including faster tooth movement and improved gum health. It also helped prevent teeth from moving out of place and minimized the risk of gum recession and bone issues. This approach can be a valuable option for adults with thin gums undergoing orthodontic treatment. [ABSTRACT FROM AUTHOR]

The aim of this study is to evaluate the long-term performance of anodized surface implants placed in native bone and followed-up for up to 17 years. Success and survival rates, prevalence of peri-implantitis, and the correlation between the presence of peri-implantitis and other clinical and demographic variables were calculated. After a mean follow-up time of 10.4 years (range: 5 to 17 years), 91.7% of 223 analyzed implants were still in function. Peri-implantitis affected 63 implants (28.3%) in 26 patients (44%). Eleven implants with peri-implantitis (4.9%) failed. Within the limits of this retrospective analysis, anodized implants appear to be prone to peri-implantitis, mainly in the posterior mandible and in patients with unsatisfactory plaque control.

The goal of this retrospective investigation was to provide evidence of the longevity of machine-surfaced implants placed in native bone and treated with the original two-stage surgical protocol. The observation times of this study covered periods of 13 to 32 years. Consecutive cases were impossible; the patients’ ages when treated reduced the number of available people as a result of death, relocation, being impossible to find, or refusal to cooperate. Mean marginal bone loss after 13 to 32 years was 1.9 ± 0.9 mm, survival rate was 97.7%, and success rate was 92.7%. Peri-implantitis occurred in a limited number of cases, with a prevalence of 1.8%. This study demonstrates long-term reliability of machined implants as a therapeutic choice. [ABSTRACT FROM AUTHOR]
