Клинико-рентгенологическая классификация протяженных имплантационных замещающих конструкций, использующихся у пациентов с полной потерей зубов

Abstract

Relevance. In domestic and foreign professional literature there is a lack of aggregated consolidated data about immediate long span implant supported prosthesis which could be fundamental in making decision making process during the treatment planning stage, as well as at the estimation of quality of implant supported prosthetics. The aim of this study – the creation of a conceptual model of the standard implant prosthetics for edentulous patients. Materials and methods. A comprehensive examination and implantation prosthetics 382 patients aged 38 to 84 years (211 women, 171 men) with 582 implant supported prosthesis of various types, supporting on implants Nobel Replace Select / Groove», «Nobel Parallel CC», «Nobel Speedy Groove», «Nobel Trefoil CC» (3775 implants). We have created a new clinical and radiographic classifcation of implant-supported prosthesis for edentulous patients. Result. As a result of the classifcation in the I (1-2 implants) class rallied 6.2% of implant supported prosthesis, to II class (3-4 implant, «TREFOIL» included) was assigned 19.2% of prostheses, to III class (5-6 implants) – 30.2% of replacement structures IV- to (7-10 implants) – 44%, and V – 0,3%. Meanwhile II, III, IV classes and I statistically revealed age differences. Conclusions: We have sorted out fve main classes, 8 subclasses and 18 groups with 34 subgroups of implant supported prosthesis based on the number of abutments, type of prosthesis, retention method and the presence of unilateral or bilateral cantilever.
