New extraction socket soft and hard tissue classification: reliability and validation

Abstract

Objectives: The aim of this study was to develop and validate a classification of extraction socket in the anterior maxillary immediately following tooth removal for immediate implantation. Material and methods: Twenty-five teeth from 25 patients (15 men and 10 women; age 18 to 51 years, average¼32.4) in frontal maxilla were extracted. The soft and hard tissue assessments in the extraction sockets were assessed using the classification system developed by 2 independent surgeons. Recommended treatment were also provided and later confirmed in the final outcomes. Weighted Cohen’s k was used to calculate interobserver reliability. Statistical analysis was performed using paired t-test, Kolmagorov-Smirnov and Marginal Homogeneity tests. Twenty-five Straumanns Standard Plus (Basel, Switzerland) dental implants were installed. If the extraction socket was graded as Type I (adequate), immediate implant installation was performed. In Type II (compromised), immediate or delayed [...].
