Abstract

Introduction

This retrospective study aimed to evaluate peri-implant marginal bone loss (MBL) and prosthetic complications between two types of locator attachments in two implant-supported mandibular overdentures.

Material and Method

From the archived records, information about patients who had two implants inserted utilizing two different types of locator attachments into the interforaminal region between November 2019 and December 2023 was obtained. Overall, 60 patients (Total = 120 implants) from the archive records of the Prosthodontics Department, Faculty of Dentistry, Mansoura University, with ages ranging from 40 to 60 (mean age 50), were included in the study. Group I (control): Overall, 30 patients who would be delivered mandibular implant overdenture using conventional locator attachments. Group II (study): Overall, 30 patients who would be delivered mandibular implant overdenture using RTx locator attachments. After the placement of the mandibular overdenture (T0), 6 months (T6), 12 months (T12), and 3 years (T3) later, the marginal bone loss (MBL) was assessed. Prosthetic complications were evaluated for both groups 3 years after prosthetic delivery.

Result

A statistically significant increase (p = 0.000) was found in MBL scores at all observation times between both groups. Group II showed a statistical increase in MBL than Group I. For prosthetic complications, no significant difference was found between both groups. Group II showed more matrix wear than Group I however, it was not statistically significant (p = 0.60).

Conclusion

Within the limitation of this study, we can conclude the following: Both types of locator attachment (conventional and RTx locator) can be used clinically with no preference concerning the frequency of prosthetic complications. From the MBL perspective, conventional locators are more favorable than RTx locators.

两种定位器固位下颌种植覆盖义齿3年临床及影像学回顾性研究。

简介：本回顾性研究旨在评估两种类型定位器附着体在两种种植支撑下颌覆盖义齿中的种植周边缘骨丢失（MBL）和修复并发症。材料和方法：从存档记录中获得了2019年11月至2023年12月期间使用两种不同类型的定位器附件将两个植入物插入椎间孔区域的患者信息。本研究共纳入曼苏拉大学牙科学院口腔修复科档案记录中的60例患者（共120例种植体），年龄40 ~ 60岁，平均年龄50岁。第一组（对照组）：总共有30例患者使用常规定位器附着体植入下颌种植覆盖义齿。第二组（研究）：总共有30例患者使用RTx定位器附着体植入下颌种植覆盖义齿。在放置下颌覆盖义齿（T0）、6个月（T6）、12个月（T12）和3年（T3）后，评估边缘骨质流失（MBL）。两组患者在植入假体3年后评估假体并发症。结果：两组患者MBL评分在各观察时段均有统计学差异（p = 0.000）。II组MBL比i组有统计学意义的增加。对于假体并发症，两组间无显著差异。治疗组基质磨损明显高于治疗组，但差异无统计学意义（p = 0.60）。结论：在本研究的限制下，我们可以得出以下结论：两种类型的定位器附件（常规定位器和RTx定位器）在临床上都可以使用，对假体并发症的频率没有偏好。从MBL的角度来看，常规定位器比RTx定位器更有利。

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
