NCT05750004 | Completed

• 1 other identifier: OSA3231001
• Study Type: interventional
• Target: 26
• Locations: 1 country

Brief Summary

The goal of this case series study is to assess the degree of angular deviation between virtual and actual computer guided immediate implant placement in anterior maxilla using the new safe angle position concept and the resultant effects on soft and hard tissues. Patients with non-restorable anterior maxillary teeth will be managed with flapless computer guided immediate implant placement fabricated using safe angle concept.

Conditions

Immediate Implants

Keywords

Immediate implant placement; computer guided; safe angle position; Angular deviation

Outcome Measures

Primary Outcomes (1)

• Angular deviations

  Angular discrepancy (measured in degrees) be-tween the planned and actual implant position respective to the center of the implant body. It is primarily ascribed to a variation in point of implant entry

  9 months

Study Arms (1)

Computer guided immediate implant placement

EXPERIMENTAL

Atraumatic extraction followed by immediate implant placement using safe angle position computer guided surgical stents.

Procedure: computer guided immediate implant placement

Interventions

computer guided immediate implant placement PROCEDURE

Atraumatic extraction followed by immediate implant placement using safe angle position computer guided surgical stents, followed by customized healing abutments. after 3 months, Impressions for final prosthesis will be done

Eligibility Criteria

• Age: 20 Years - 50 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Adults ≥ 20 years to 50 years of both genders and in good general health.
• Maxillary anterior tooth that cannot be retained due to non-periodontitis, including fracture, endodontic failure, and root resorption, bounded by natural teeth.
• Intact buccal bone plate (via CBCT).
• The extraction socket has at least 3-5 mm apical bone.

You may not qualify if:

• \. Smokers 2. Pregnant and lactating females: Pregnancy as this will limit recording the outcome data eg: CBCT.
• \. Medically compromised patients, as uncontrolled diabetic patients, patients taking bisphosphonates injection for treatment of osteoporosis, patients with active cardiac diseases, patients undergoing radiotherapy or chemotherapy, or any other medical and general contraindications for the surgical procedure (i.e. ASA score ≥III) (31) 4. Patients with active infection related at the site of implant/bone graft placement.
• \. Patients with untreated active periodontal diseases. 6. Patients with parafunctional habits. 7. Refuse to participate in this study.
