Brief Summary

This study aims to clinically and radiographically evaluate the efficacy of Densah burs (osseodensification) compared to the modified conventional drilling technique for early-loaded dental implants in the posterior maxilla.

Conditions

Jaw, Edentulous, Partially; Dental Implant Failure; Bone Resorption

Keywords

Densah Burs; Osseodensification; Dental Implants; Early Loading; Implant Stability; Posterior Maxilla

Outcome Measures

Primary Outcomes (1)

• Implant Stability Quotient (ISQ)

  Implant stability measured using Resonance Frequency Analysis (RFA) with the Osstell Mentor device and SmartPeg. Measurements were recorded in four directions (every 90 degrees) and averaged per implant to provide an ISQ score (scale: 1 to 100, where higher scores indicate greater stability).

  12 months

Study Arms (2)

Densah Bur Group

EXPERIMENTAL

Osteotomy site preparation using Densah burs in reverse (counterclockwise) condensing mode at 800-1500 rpm with copious sterile irrigation and gentle pumping motion, followed by early loading after 2 months.

Procedure: Densah Bur Osseodensification

Modified Conventional Drilling Group

EXPERIMENTAL

Osteotomy site preparation using conventional drills sequentially in a clockwise direction, with the final drill operated in a counterclockwise direction, followed by early loading after 2 months.

Procedure: Modified Conventional Drilling

Interventions

Densah Bur Osseodensification PROCEDURE

Osteotomy site preparation using sequential Densah burs in reverse (counterclockwise) condensing mode at 800-1500 rpm with copious sterile saline irrigation and gentle pumping motion to preserve and compact bone.

Densah Bur Group

Modified Conventional Drilling PROCEDURE

Sequential conventional drilling with the final drill operated in counterclockwise rotation to condense bone.

Modified Conventional Drilling Group

Eligibility Criteria

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

You may qualify if:

• Patients missing one or more posterior maxillary teeth (premolars or molars).
• Age range between 18 and 50 years.
• Residual vertical bone height of 10 mm or more below the maxillary sinus floor.
• Alveolar ridge width of 6 mm or more.
• Minimum crown height space of 8 mm.
• Good oral hygiene.
• Non-smokers.
• Absence of systemic diseases that absolutely contraindicate implant surgery.
• No parafunctional habits such as bruxism or clenching.
• Patient compliance and willingness to attend all follow-up appointments.

You may not qualify if:

• Pathological lesions or retained root tips at the planned surgical site.
• Use of medications affecting bone metabolism or healing (e.g., bisphosphonates).
• Untreated periodontal disease or poor oral hygiene.
• Pregnancy.
