Abstract

ABSTRACT
Introduction: The locator attachment has been widely and successfully used to
support dentures has dual retention and is available in different heights with different
retention values; in addition, their repair and replacement are quick and straight
forward. Aim: The aim of this study was to compare clinically and radio graphically
the biological effect of two different locator heights on peri-implant bone
width and probing depth in mandibular implant overdenture wearers. Materials and
methods: Conventional complete dentures were constructed for twelve completely
edentulous male patients, chosen from Out-clinic of faculty of dentistry Suez Canal
University. Two implant were inserted in the lower cusped region then the patients
divided randomly into two groups Group A(GA): Six patients received implant retained
over denture with 1mm locator height. Group B (GB): Six patients received implant
retained over denture with 3mm locator height, the follow up both clinically and radiography
were taken at 0, 6, 12 and 18 months starting from the first day of over denture
attachment pick up. Peri-implant bone width and probing depth were estimated through
the evaluation periods. Results: It was found that the reduction in the peri-implant
alveolar buccolingual width and probing depth around the implants were higher in GA
than GB at all follow up periods, except for the last follow up period. Conclusion: The
locator height has a biological effect on bone width and probing depth as the higher
locator height the more preservation of peri-implant bone.
