With respect to clinical outcome measures, the available data do not indicate a difference between ultrasonic/sonic and manual debridement in the treatment of chronic periodontitis for single-rooted teeth; however, the evidence for this is not very strong. In addition, ultrasonic/sonic subgingival debridement requires less time than hand instrumentation. Further research is needed to assess the efficacy of machine-driven debridement on multirooted teeth and clinical outcome variables having tangible benefit to the patients should be used.
The novel low-abrasive air polishing powder is superior to curets in removing subgingival plaque at interdental sites with up to 5 mm probing depth in PMT.
The aim of this study was to report the outcome of the management of alveolar crest vertical defects using the tunnel technique approach associated with autogenous bone blocks prior to implant placement in 10 partially dentate consecutively treated patients. Four clinical linear measurements were taken: maximal extension of the vertical defect (VD) at the time of the augmentation procedure (time 0), vertical bone graft (VBG) recorded at time 0, bone resorption at implant placement (time 1), and bone resorption during implant healing at the time of abutment connection (time 2). All patients healed uneventfully, and no complications were recorded. Both mean VD and VBG at time 0 were 6.50 ± 1.43 mm. Mean bone resorption at time 1 was 0.30 ± 0.48 mm and mean bone resorption at time 2 was 0.25 ± 0.26 mm, yielding an overall vertical bone remodeling of 0.55 ± 0.49 mm (8.4%) after 8 months. This study supports the capability of a minimally invasive approach to regenerate bone in vertical defects prior to implant placement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
