Abstract

UNLABELLED

The extraction of teeth involves the elimination of extremely sensitive periodontal mechanoreceptors, which play an important role in oral sensory perception.

OBJECTIVES

The aim of this study was to evaluate the recovery of interocclusal sensory perception for micro-thickness in individuals with different types of implant-supported prostheses.

MATERIALS AND METHODS

Wearers of complete dentures (CDs) comprised the negative control group (group A, n=17). The experimental group consisted of wearers of prostheses supported by osseointegrated implants (Group B, n=29), which was subsequently divided into 4 subgroups: B(1) (n=5)--implant supported overdentures (ISO) occluding with CD; B(2) (n=6)--implant-supported fixed prostheses (ISFP) occluding with CD; B(3) (n=8)--wearers of maxillary and mandibular ISFP, and B(4) (n=10)--ISFP occluding with natural dentition (ND). Individuals with ND represented the positive control group (Group C, n=24). Aluminum foils measuring 10 microm, 24 microm, 30 microm, 50 microm, 80 microm, and 104 microm thickness were placed within the premolar area, adding up to 120 tests for each individual.

RESULTS

The mean tactile thresholds of groups A, B1, B2, B3, B4, and C were 92 microm, 27 microm, 27 microm, 14 microm, 10 microm, and 10 microm, respectively. [Correction added after publication online 18 April 2008: in the preceding sentence 92 microm, 27 microm, 14 microm, 10 microm and 10 microm, was corrected to 92 microm, 27 microm, 27 microm, 14 microm, 10 microm and 10 microm]. The Kruskal-Wallis test revealed significant difference among groups (P<0.05). The Dunn test revealed that group A was statistically different from groups C, B(3), and B(4), and that B(1) and B(2) were statistically different from group C.

CONCLUSION

Progressive recovery of osseoperception as a function of the combination of implant-supported prostheses could be observed. Moreover, ISO and/or ISFP combinations may similarly maximize the recovery of osseoperception.

摘要

未标注

拔牙会消除极其敏感的牙周机械感受器，这些感受器在口腔感觉感知中起重要作用。

目的

本研究旨在评估不同类型种植体支持义齿个体间咬合间微厚度感觉感知的恢复情况。

材料与方法

全口义齿佩戴者组成阴性对照组（A组，n = 17）。实验组由骨结合种植体支持的义齿佩戴者组成（B组，n = 29），随后分为4个亚组：B(1)（n = 5）——种植体支持覆盖义齿（ISO）与全口义齿咬合；B(2)（n = 6）——种植体支持固定义齿（ISFP）与全口义齿咬合；B(3)（n = 8）——上颌和下颌ISFP佩戴者，以及B(4)（n = 10）——ISFP与天然牙列（ND）咬合。天然牙列个体组成阳性对照组（C组，n = 24）。将厚度为10微米、24微米、30微米、50微米、80微米和104微米的铝箔放置在前磨牙区域，每个个体共进行120次测试。

结果

A组、B1组、B2组、B3组、B4组和C组的平均触觉阈值分别为92微米、27微米、27微米、14微米、10微米和10微米。[2008年4月18日在线发表后添加的更正：在上一句中，92微米、27微米、14微米、10微米和10微米更正为92微米、27微米、27微米、14微米、10微米和10微米]。Kruskal - Wallis检验显示各组间存在显著差异（P < 0.05）。Dunn检验显示A组与C组、B(3)组和B(4)组在统计学上有差异，且B(1)组和B(2)组与C组在统计学上有差异。
