Abstract

Bone loss around implant necks has traditionally been regarded as an indicator of implant success over the long term. Both surgical and prosthetic variables have been linked to premature marginal bone loss. Early marginal bone loss (MBL) >0.44 mm in the first six months following prosthetic loading is a risk indication for peri-implant bone loss development, according to new research on crystal-level implants. To determine the effect of crown height of dental implant on marginal bone loss. This is a retrospective study conducted using the patients’ records. The sample size was 50 teeth. Patients’ age, gender, and medical status were recorded as well as the implant’s location, diameter, and type of opposing tooth, guided bone regeneration, crown height, implant length, crown-to-implant ratios, and type of platforms. Patients having had dental implants before 3 to 5 years at Riyadh Elm University (REU) hospitals and aged above 18 years old were included in this study. Pearson’s correlation test findings between crown height and the follow-up MBL. It can be noted that Pearson’s correlation value was .116, which indicates that there is a positive correlation between crown height and the follow-up MBL. However, this positive correlation was not statistically significant as the P-value was observed to be .422. There is no evidence of implant crown height affecting marginal bone loss.
