Three-Phase Surface Treatment for Single Implants: An Observational Study.
Objectives: Implant surfaces constantly undergo modifications to enhance immediate-loading procedures and improve stability in poor-quality bone, which has allowed the rehabilitation of edentulous patients to become a predictable treatment. The aim of this study is to assess the clinical behavior of peri-implant mucosa, bone-loss, implant stability quotient (ISQ) and survival rate of three-phase-treated-surface Titanium implants over 5 years.
Methods: A total of 78 patients attending the Surgery and Orofacial Implantology Service of Madrid Hospital participated in this longitudinal retrospective study. 111 implants (Defcon®, TSA, Impladent) were used. CP-12 probes, ISQ beacon and radiological equipment were used for clinical surveillance, periodontal probing, ISQ evaluation and assessment of implant survival rate. Statistical analyses were performed using SPSS 17.
Results: Implants were located with greater frequency in 46 and 14 sites (11,8% and 12,7% respectively). Average periodontal probing was 1,75mm, whilst the most frequent values were 2,00 mm (32,80%), 1,00 mm (29,40%) and 1,50 mm (17,20%). Average ISQ was 68, whilst the most prevalent ISQ values were 66 (27,3%), 67 (21,2%) and 64 (15,2%). No significant correlation was found between age and bone-loss (P=0,007) or ISQ
values (P=0,04), but it was observed that periodontal probing values increased significantly with age (P=0,096). Greater bone-loss is significantly associated with poorer ISQ (P=0,00) and periodontal probing
(P=0,007). No statistically-significant differences were found for bone-loss, ISQ values or periodontal probing
regarding sex, anatomical regions of the arch or implant length. Success rate of 99,1% (1 failure).
Results are difficult to compare to those obtained in other studies due to the lack of investigations with a 5-year-long period of monitoring. Average probing in this study (1,75mm) was similar or slightly lower than data
displayed in other reports.
Conclusions: All data obtained regarding clinical behavior of peri-implant mucosa, bone-loss, ISQ and survival rate provides satisfactory results.
