Evaluation of Corrective Surgery Versus Dental Implants in Compromised Mandibular Molars

June 5, 2026 updated by: yomna tarek, Ain Shams University

Clinical and Radiographic Outcomes of Corrective Surgery Versus Dental Implant Treatment for Management of Compromised Permanent Mandibular Molars (An In-vivo Study)

This study seeks to assess the clinical, radiographic, and patient-reported outcomes of hemisection versus implant over a 12 months period, generating robust evidence to guide clinical decision-making and enhance patient care.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Good oral hygiene and motivation for follow-up care.
  • Ability to understand and sign informed consent.
  • Localized Root/Periodontal Disease: Severe attachment loss or bone loss (e.g., severe localized periodontitis) affecting the mesial root, while the other root remains healthy.
  • Furcation Involvement: Class II or III furcation involvements where the disease cannot be treated by conventional methods.
  • Vertical root fracture confined to the mesial root.
  • Non-treatable perforation in the mesial root.
  • Extensive sub-gingival root caries affecting the mesial root.
  • Extensive un-treatable internal and external root resorption related to the mesial root.

Exclusion Criteria:

  • Uncontrolled systemic diseases (e.g., diabetes mellitus, bleeding disorders, immunosuppression).
  • Fused or poorly shaped roots,
  • Active periodontal or endodontic infection at adjacent teeth that may interfere with treatment outcomes.
  • Severe bruxism or occlusal parafunction.
  • History of radiation therapy in the head and neck region.
  • Pregnancy or lactation.
  • Poor compliance or inability to attend follow-up visits.
  • Smoking more than 10 cigarettes per day.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Hemisection
patients in this group will have hemi sectioning to their compromised mandibular molars
Procedure: hemi sectioning
one root will be extracted and the other root will be preserved
No Intervention: dental implants
patients will undergo extraction and replaced with dental implants

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
• Regulation of clinical signs and symptoms
Time Frame: 12 months
Patient-reported outcomes, including satisfaction, masticatory efficiency, and oral comfort measured by a visual analog scale (VAS).
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of radiographic bone changes
Time Frame: 12 months
  • Radiographic bone level changes around the retained root or implant.
  • Detection of any radiographic signs of pathology or treatment failure. Measurements will be recorded in millimeters (mm) using digital radiographic software calibration tools.
12 months
