Immediate load protocol for anterior maxilla with cortical bone from mandibular ramus.

Area of Science:

• Dental Implantology
• Oral and Maxillofacial Surgery
• Bone Grafting Techniques

Background:

• Bone grafting is crucial for dental implant placement in atrophic maxillas.
• Immediate loading protocols offer potential benefits in treatment time.
• Autogenous block cortical grafts from the mandible are a reliable source for maxillary augmentation.

Purpose of the Study:

• To assess the efficacy of immediate nonfunctional loading for single dental implants.
• To evaluate implants placed in anterior maxilla augmented with mandibular block cortical grafts.
• To determine the predictability of this protocol in a clinical setting.

Main Methods:

• 19 hydroxyapatite-coated dental implants were placed in 19 patients.
• Implants were immediately loaded with provisional restorations within 3 days, out of occlusion.
• Definitive restorations were placed after 12 weeks.

Main Results:

• All 19 implants maintained function throughout the 1-year observation period.
• No implant failures were reported during the study.
• The protocol demonstrated successful osseointegration and prosthetic stability.

Conclusions:

• Immediate nonfunctional loading is a predictable protocol for single implants in bone-grafted anterior maxillas.
• This approach can be successfully applied in select patient cases.
• Further research may explore long-term outcomes and broader applications.
