Background/Aim: The stability of peri-implant tissues is crucial for the long-term success of dental implant treatments. A new cervical implant design has been developed to address the challenges associated with peri-implant tissue stability, featuring a concave cervical portion to increase tissue volume in this area. The present study aimed to clinically evaluate the effectiveness of the new cervical implant design in maintaining peri-implant tissue stability. Materials and Methods: Five clinical cases involving completely edentulous patients were selected, in which 25 implants were installed. The marginal bone level around each implant was assessed at three different time points—T0: immediately after the prosthesis installation, T1: 6 months post installation, and T2: at the last control visit, up to 38 months later. Measurements were taken to analyze changes in marginal bone levels (MBLs) and the keratinized mucosa (KM) over time. Furthermore, the keratinized mucosa (KM) around the implants was evaluated. Results: The mean and standard deviation values of the marginal bone levels at each time point were as follows—T0: 0.59 ± 0.55 mm; T1: 1.41 ± 0.59 mm; T2: 1.76 ± 0.69 mm. Statistical analysis showed significant differences across the time points (ANOVA p < 0.0001). The overall mean KM values were 3.85 mm for T1 and T2, showing the stability of the peri-implant soft tissues at ≥1-year controls. Conclusion: Within the limitations of the present study, the results showed that the Collo implants presented measured MBL values increasing within the time range analyzed in each case but within the normal values cited in the literature for these types of rehabilitation treatments. However, the measured KM values presented, in all cases, an average above the values referenced in the literature as a minimum for maintaining the health of the peri-implant tissues.
Background and Objectives: This study aimed to evaluate marginal bone level (MBL) changes in implant-supported rehabilitation based on patient demographics, implant location, transmucosal abutment height, and crown emergence profile. Materials and Methods: A total of 50 patients (28 females and 22 males), with 111 implant–abutment (IA) sets, were analyzed. The mean age was 65.2 ± 10.9 years (range: 33–81). Implants were placed in the maxilla (68.5%) and mandible (31.5%), with an average evaluation period of 12.7 ± 4.1 months. MBL changes at mesial (MBLm) and distal (MBLd) sites were recorded and analyzed based on sex, age, implant location, abutment transmucosal height, and crown emergence profile. Statistical comparisons were performed using Bonferroni’s multiple comparison test and one-way ANOVA with Tukey’s post hoc test. Results: MBL changes did not show significant differences based on sex (p > 0.05) or age group (p > 0.05). However, maxillary implants exhibited greater bone loss than mandibular implants, though this difference was not statistically significant. Transmucosal abutment height (TMh) significantly influenced MBL, with taller abutments (TMh3: −1.07 ± 0.93 mm) showing less bone loss than shorter abutments (TMh1: −2.11 ± 1.82 mm) (p < 0.05). Crown emergence profile also affected MBL, particularly in the distal emergence profile, where design 1 exhibited the least bone loss compared to designs 2 and 3 (p = 0.0176). Conclusions: The study findings suggest that transmucosal abutment height and crown emergence profile significantly influence peri-implant bone stability. Transmucosal abutment height (> 2.5 mm) was associated with reduced bone loss. Further research is recommended to evaluate the long-term effects on peri-implant bone maintenance.
A ozonioterapia parece demonstrar potencial como tratamento adjuvante no manejo de doenças peri-implantares e na promoção da cicatrização após cirurgias com implantes. Portanto, o objetivo desta revisão integrativa foi avaliar o papel da ozonioterapia na implantodontia. Foi realizada uma busca nas bases de dados PubMed da National Library of Medicine e Web of Science (WOS), além de busca manual. Foram incluídos artigos publicados em inglês ou português, desde que abordassem o uso da ozonioterapia em implantes dentários. Os critérios de exclusão incluíram textos incompletos, teses, dissertações, relatórios técnicos e estudos que não tratassem diretamente do foco da revisão. A seleção final incluiu 15 estudos, compostos por ensaios clínicos, estudos in vivo e in vitro. A maioria dos estudos indicou um impacto positivo da ozonioterapia na redução da inflamação, aceleração da cicatrização e controle da dor pós-operatória. A ausência de estudos primários com metodologias robustas dificulta a recomendação definitiva da ozonioterapia como tratamento adjuvante padrão na implantodontia. A ozonioterapia demonstra potencial como tratamento adjuvante no manejo de doenças peri-implantares e na promoção da cicatrização após cirurgias com implantes. Embora seus efeitos na osseointegração exijam mais investigação, as evidências apoiam seus benefícios terapêuticos na redução da dor e inflamação. São necessários estudos primários mais rigorosos para confirmar essas conclusões e estabelecer protocolos clínicos padronizados, incluindo dosagem e métodos de aplicação, a fim de garantir uma integração segura e eficaz da ozonioterapia nos tratamentos com implantes dentários.
