Dental implants in the atrophic maxilla experience higher strains, especially with poor bone quality. Finite-element analysis shows bone quantity and quality significantly impact implant success rates.

Area of Science:

Biomaterials science
Dental implantology
Biomechanics

Background:

Oral implants in the maxilla, particularly the posterior region, exhibit lower success rates compared to the mandible.
Insufficient bone quantity and quality are primary suspected reasons for this disparity.

Purpose of the Study:

To analyze stress and strain distributions around loaded dental implants.
To compare these distributions in normal versus atrophic maxillary bone conditions using finite-element (FE) analysis.

Main Methods:

Generation of FE models for solitary implants.
Simulation of static axial loads on implants within varied bone conditions and lengths.
Calculation of resultant stresses and strains in adjacent bone tissue.

Main Results:

Bone quality and quantity significantly reduce bone strain near the implant surface.
Increased spongy bone content leads to more homogeneous stress distribution.
Atrophic bone dimensions combined with poor bone quality result in supraphysiological surface strains (> 6,000 microstrains).
Reduced bone height had less impact on stress/strain alterations compared to poor bone quality.

Conclusions:

Supraphysiological bone strains are anticipated under mechanical loading in atrophic maxillary conditions.
Bone quality is a critical factor influencing implant stress and strain environments.
