FACTORI DE RISC ESTETICI ÎN IMPLANTOLOGIE.

Definitions: The aesthetic risk factors according to Renouard-Rangert11 represent an analytical approach to the most relevant aesthetic aspects of implant-borne rehabilitation. They can be used to foresee the aesthetic outcome of a case yet to be treated, or to analyse the achieved result of an already completed case. The purpose of this paper is to present a simple formula which enables the calculation of an aesthetic score value for any implant-borne rehabilitation. Materials and methods: The paper illustrates every original Renouard-Rangert aesthetic risk factor using an original case. Every risk factor is assigned a specific value ranging from -2 to +2. The sum of these values represents the final aesthetic score value of a specific implant-borne rehabilitation. Results: The subjective perception of a specific rehabilitation, as to it being aesthetic or not, is matched to our aesthetic score value. Discussion: Although the original authors accurately classified and described several aesthetic risk factors, they failed to come up with a calculation method intended to produce an overall aesthetic score value, as they did for the biomechanical risk factors. Our calculation method is actually as criticisable as the Renouard-Rangert biomechanical score value calculation because each and every aesthetic risk factor has been allotted a different value on a purely subjective basis. Conclusions: The aesthetic score value seems to be an efficient calculation method for prospective and retrospective aesthetic result assessment of implant-borne rehabilitations. In order to switch from presumption to certainty, a prospective double-blind controlled study which compares the prospective aesthetic score value to the retrospective one is needed.
