Estimation of crestal bone loss in single posterior implant assessed at different post operative follow ups: A cone beam computed tomography based original research study

Abstract

Aim:The ultimate aim of this study was to assess crestal bone loss in single posterior implant
assessed at different post operative follow ups using cone beam computed tomography.
Materials & Methods: The study was conducted in the department of oral and maxillofacial
surgery wherein cone beam computed tomography was used as standard radiography to
determine exact bone levels at two post osteotomy phases. Total twelve subjects were selected
by randomized sampling procedure which included both male and females in the age range of
26-41 years. Actual bone loss evaluations were completed by comparative estimation of cone
beam computed tomography records (of one month and six month post operative follow up). It
was attempted at all four surfaces (mesial, distal, buccal and lingual) at mandibular first molar
region. All data was entered in master chart and sent for basic statistical analysis. P value less
than 0.05 was considered significant (p< 0.05).
Statistical Analysis and Results: Statistical software i.e., Statistical Package for the Social
Sciences version 21.0was utilized for analysis. Maximum 5 participants were reported in first
age group of 26-29 years whereas minimum one participant was reported in fourth age group of
38-41 years. Maximum mean crestal bone loss was confirmed at lingual surface and minimum
mean bone loss was recognized at buccal surface at second follow-up stage. Level of
significance (p value) was highly significance for distal and lingual surfaces. 95% coefficient
interval was measured maximum and minimum at distal and mesial surfaces. Pearson chi-square
value was maximum at buccal surface and minimum at distal surface.
Conclusion: Within the limitations of the study, authorconcluded few very striking
assumptions.Considerablecrestal bone loss was noticed in all patients.Maximum mean bone loss
was confirmed at lingual sides while minimum bone loss was seen at buccal sides. Because the
implant crestalbone loss is very subjective and depends on several host related factors, inferences
of this study should be clinically correlated.
