Dental Implant
Conditions
Brief summary
Background: When placing a dental implant, it is not always possible to place it exactly in the same position as the tooth that it replaced. That might be because of how the gums and mouth are shaped, since some bone is always lost after a tooth is extracted. Researchers want to study the records of people who have had dental implants. They want to check to see how much difference there is between how the implant is positioned and how the same tooth on the other side is positioned. They also want to compare how the implant is positioned compared to the tooth it replaced, when that is possible in the dental record. Study design: This study will not enroll any participants. The researchers will search the database of patient records at the study clinic to find people who have had dental implants of a single molar tooth. Then they will look at them to find records that include good images that they can use to compare the implant and tooth positions. Researchers will then analyze the findings and write a review article.
Detailed description
This is a retrospective chart review. Specifically, the clinic e-chart system will be used to locate patients who received implant surgery. E-charts from January 1, 2016, to January 6, 2025, with pre- and post-implant surgery tomography (CBCT) documentation will be identified and used for this study. Demographic and clinical data (age, sex, systemic conditions, implant details and surgical treatment outcomes) related to these cases will be collected. Radiographic measurements will include the following: * On tomography: 1. Buccolingual axial inclination of natural molars and implants. 2. Mesiodistal axial inclination of natural molars and implants. 3. Presence/absence of fenestration and/or dehiscence around implants 4. Proximity to mandibular canal and/or foramen mentale * On Panoramic radiograph: Mesiodistal axial inclination of natural molars and implants.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Replaced Tooth Comparison | Baseline (prior to tooth extraction), day 1 of implant placement, day 1 of crown placement (4-6 months after implant placement) | Difference in buccolingual and mesiodistal angulations of placed implant compared with pre-extraction natural tooth. |
| Contralateral Tooth Comparison | Day 1 of implant placement, day 1 of crown placement (4-6 months after implant placement) | Difference in buccolingual and mesiodistal angulations of placed implant compared with contralateral natural molar. |
