CBCT Teeth Case Analysis – Apical Infection Adjacent to Dental Implant

Case Overview

This CBCT image shows a posterior mandibular area with a natural molar next to an existing dental implant. The natural tooth presents a clear apical radiolucency, indicating infection at the root apex. Bone density changes are visible between the infected tooth and the implant site.

Full Analysis and Diagnosis

Clinical Findings

• Natural molar with deep restoration

• Visible apical lesion at root tip

• Adjacent implant appears integrated

• Localized bone loss near apical area

• Cortical bone still intact

Radiographic Interpretation

• Periapical radiolucency suggests chronic apical periodontitis

• Bone trabeculation is reduced near infection site

• Infection is in close proximity to implant threads

• No immediate implant mobility, but risk is present

Diagnosis

• Chronic apical infection of natural tooth

• Secondary risk of peri-implant bone involvement

Time Frame to Heal

With Proper Treatment

• Infection control: 7–14 days

• Pain and inflammation reduction: within 1 week

• Bone healing begins: 4–6 weeks

• Radiographic bone recovery: 3–6 months

Without Treatment

• Infection may spread toward implant

• Progressive bone loss

• Increased risk of peri-implantitis

• Possible implant failure

Process to Execute (14-Day Window)

Days 1–3

• Clinical exam and CBCT evaluation

• Identify infection source

• Prescribe antibiotics if indicated

Days 4–7

• Root canal treatment or retreatment

• Drainage if abscess is present

• Occlusal adjustment if needed

Days 8–14

• Follow-up assessment

• Monitor implant stability

• Evaluate soft tissue healing

Issues That Will Scale Up If Untreated

• Expansion of apical lesion

• Bone loss reaching implant surface

• Chronic pain and swelling

• Surgical intervention required

• Implant loss in advanced cases

Clinical Comments

Early endodontic treatment is strongly advised. The implant is currently stable, but adjacent apical infection poses a serious long-term risk. Timely intervention can preserve both the tooth and the implant.
