Site 44: Apical implant position + close proximity to mental foramen
A 4x8mm cylinder was overlaid on the adjacent images at site 44, and the collar of this implant is positioned at the midroot level of the adjacent tooth. In addition, the apical region of the implant is in close proximity to the mental foramen. The apex of the implant should be lingually oriented in order to avoid the mental foramen.
Site 45: Adequate bone
A 4x10mm cylinder was overlaid on the adjacent images at site 45. Adequate bone exists for implant placement at this site.
1. Widened PDL spaces of tooth 26MB+DB
The periapical periodontal ligament spaces of the mesiobuccal and distobuccal roots of tooth 26 are slightly widened. These roots are unobturated, and may require endodontic treatment.
2. Extruded endodontic sealer at tooth 25
Endodontic sealer has been extruded through the apical foramen of tooth 25. This is an incidental finding with no significance. No periapical pathology is present.
3. Left maxillary sinus mucositis
The portion of the left maxillary sinus that is visible in the field of view is completely opacified. This is suggestive of the presence of moderate or severe left maxillary sinus mucositis.
4. Palatine tonsilloliths
Tonsilloliths are present in the palatine tonsils. This is an incidental finding with no clinical significance because tonsilloliths exfoliate spontaneously.
5. Monckeberg's arteriosclerosis
Calcifications are visible in the tunica media of the left internal carotid artery at the level of C3. This is an incidental finding with no proven clinical significance and is suggestive of the presence of Monckeberg's arteriosclerosis.
6. Cervical degenerative joint disease
Osteophytes and subchondral sclerosis are present in the articular regions of the cervical vertebrae. This is a common incidental finding with no clinical significance that is suggestive of cervical degenerative joint disease.
7. Pneumatocyst in C3
A gas filled cavity is present in the left lateral articulating region of the third cervical vertebra. This represents a pneumatocyst, which is a sign of cervical degenerative joint disease.
Site 35: Borderline bone levels
A 4x10mm cylinder was overlaid on the adjacent images at site 35. Barely enough bone exists to cover the cylinder at this site.
Axial views of site 35
These axial cross-sectional images demonstrate the proximity of the apex of the putative implant at site 35 to the mental foramen.
Normal tooth 36
The roots of tooth 36 appear normal radiographically. No signs of endodontic or periradicular pathology are present. No periodontal bone loss is present.
