Brief Summary

The goal of this randomized clinical trial is to compare the primary stability of double-thread and triple-thread dental implant designs in patients requiring implant placement in the posterior maxilla. The main question it aims to answer is whether implant thread design influences primary implant stability in the posterior maxilla. Participants will be randomly assigned to one of two groups. Group A will receive a double-thread dental implant, while Group B will receive a triple-thread dental implant. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).implant stability using ISQ will also be evaluated at 3 months

Conditions

Dental Implant; Primary Stability of the Implants

Keywords

dental implant; primary implant stability; primary stability; thread design; double thread; triple thread

Outcome Measures

Primary Outcomes (1)

• insertion torque

  The primary outcome of this study will be the insertion torque, expressed in Newton-centimeter (Ncm). Measurements will be performed using a surgical motor/torque wrench and recorded at the time of implant placement (T0).

  at the time of implant placement T0

Secondary Outcomes (1)

• implant stability (ISQ)

  3 months

Study Arms (2)

Double-Thread Implant Group

EXPERIMENTAL

Participants assigned to this arm will receive a double-thread dental implant in the posterior maxilla

Device: double thread dental implant

Triple-thread implant

EXPERIMENTAL

Participants assigned to this group will receive a triple-thread dental implant placed in the posterior maxilla. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).

Device: triple thread dental implant

Interventions

triple thread dental implant DEVICE

Participants assigned to this group will receive a triple-thread dental implant placed in the posterior maxilla. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).

Triple-thread implant

double thread dental implant DEVICE

Participants assigned to this group will receive a double-thread dental implant placed in the posterior maxilla. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).

Eligibility Criteria

• Age: 20 Years - 55 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Patients aged 20-55 years.
• Medically healthy individuals without any systemic disease that affects bone healing (e.g., uncontrolled diabetes, osteoporosis).
• Patients requiring dental implants in the posterior maxilla.
• Adequate bone volume for implant placement.
• Signed informed consent for participation in the study.

You may not qualify if:

• Smokers (due to the potential negative impact on bone healing and implant success).
• Pregnant or breastfeeding women.
• Patients with a history of radiotherapy or chemotherapy.
• Patients with severe periodontal disease.
• Individuals with a history of allergic reactions to implant materials.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: PARTICIPANT
• Masking Details: Participants will be blinded to the type of implant thread design received. The investigator will not be blinded because the investigator performs the implant placement and measures implant stability.
• Purpose: OTHER
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: masters candidate

Model Details: participants will be randomly assigned to two parallel groups. One group will receive double-thread dental implants, while the other group will receive triple-thread dental implants. Primary implant stability will be compared between the two groups
