Four Techniques you need to know before placing Implants in thin Ridges
Hisham abada

Everyday Dentists are challenged by patients who are eager to have their missing teeth replaced but as soon as they realize that their
edentulous area is 4 mm or less in thickness they start thinking about different modalities other than dental implants.
This Lecture will help the dentist understand the other techniques out there that will allow the dentist to place implants in thin ridges
on the same day of treatment without having to do extensive bone augmentation surgeries or wait for months before placing Implants.
The Objective of this lecture:
1 Take home methods that they can apply in their practice the next day.
2 Understanding the different techniques and tools out there that will impact their patients and their practice.
3 Understanding the techniques by following a step by step protocol that's fully supported by published literature and articles.
Reliability of Overbite Depth Indicator (ODI) and Antero-Posterior Dysplasia Indicator (APDI) in the
Assessment of Different Vertical and Sagittal Dental Patterns: A Receiver Operating Characteristic
(ROC) Analysis

INTRODUCTION: In orthodontic diagnosis, use of a single parameter may not be appropriate to diagnose a jaw discrepancy.
Therefore, use of composite cephalometric measurements as the sum of inter-planar angles may provide more reliable information
of skeletal feature. Hence, the aim of present study was to investigate the diagnostic validity of overbite depth indicator (ODI) and
antero-posterior dysplasia indicator (APDI) in assessing the vertical and sagittal malocclusions.
MATERIAL AND METHODS: Orthodontic records (lateral cephalograms & dental casts) of 90 subjects aged 10-30 years were
collected from the dental clinics of AKUH. The sample was divided into three groups for ODI and APDI each on the basis of
overbite and molar classification, respectively. The sum of components of ODI and APDI were calculated for each group. Data
were analyzed using SPSS Windows version 19 software. Mann-Whitney U Test was applied to compare the variables between the
gender and age groups. Kruskal-Wallis test was performed to compare the sum of ODI and APDI in the study groups, respectively.
Receiver operating characteristic analysis (ROC) was applied to confirm the diagnostic validity. A p-value of ≤ 0.05 was considered
as statistically significant.
RESULTS: In the vertical component analysis, the ODI significantly differentiated between the normal over-bite, deep-bite, and
open-bite groups, whereas, the APDI significantly differentiated between the three molar groups in the sagittal analysis. The ROC
analysis showed that the APDI matched the molar relationship in 88% of subjects, and the ODI matched the amount of incisor
overbite in 91% cases.
CONCLUSIONS: A high value of ODI results in a skeletal deep-bite and low value of ODI results in a skeletal open-bite. On the other
hand, a high value of APDI results in a skeletal Class III pattern and low value of APDI results in a skeletal Class II pattern.
