Short Implant Versus Crestal Standard Length Implant to Retain Class 1 Removable Partial Denture.

Objective: To report the implant survival rates, clinical, and radiographic outcomes of subcrestal short implant versus crestal standard length implant supported removable partial denture (RPD).

30 individuals with at least 2 adjacent missing teeth bilaterally were included.to support class Ι RPD with conventional loading protocol were chosen for this research. Each participant received 2 implants in a split mouth design, one side received 1 subcrestal short implant and the contralateral side crestal standard length implant. Plaque index (PI), bleeding on probing (BOP), probing depth (PD), radiographic crestal bone level (CBL) and implant survival rate were evaluated. at implant placement (T0), restoration delivery (T1), and 3-year follow-up after loading (T2). MBL was calculated as the change in distance from the implant-abutment interface to the first radiographically visible bone-implant contact. A repeated-measures mixed ANOVA followed by a paired Student's t-test with the Bonferroni correction was used for statistical analysis. p \< 0.05 was considered statistically significant
