Immediate Occlusal versus Non-Occlusal Loading of Implants: A Randomized Clinical Pilot Study

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Immediate occlusal and non-occlusal loading protocols for dental implants are debated, with success varying by case.
• Preoperative planning and intraoperative accuracy are crucial for implant-supported reconstructions in edentulous jaws.

Purpose of the Study:

• To compare the clinical outcomes of immediate occlusal loading versus non-occlusal loading for posterior dental implants.

Main Methods:

• 52 screw-type implants in 19 patients were randomized into two groups: immediate occlusal loading (21 implants) or non-occlusal loading (31 implants).
• Restorations were screw-retained or cemented. Outcomes, including marginal bone defects (MBD), implant survival, and success, were assessed at 12 months.

Main Results:

• Both groups exhibited similar MBD levels.
• Implant survival and success rates were 100% in both groups, with no significant intergroup differences observed.

Conclusions:

• Immediate restorations with occlusal loading in partially edentulous mandibles yielded successful 12-month clinical and radiographic results.
• Further long-term studies are required to validate immediate functional loading as a standard treatment for partially edentulous jaws.
