Summary

This study was conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University. A prospective non-controlled clinical study was performed on ten patients with compromised zygomaticomaxillary bone. Surgical intervention was carried out using a customized surgical guide.

Pre-surgical planning was performed using computed tomography (CT) scans for each patient. Surgical guides were fabricated using direct metal laser sintering technology. Zygomatic implants were inserted using a guided surgical protocol and specialized instruments.

Postoperative CT scans were obtained to evaluate deviations between the planned and actual implant positions. Accuracy was assessed by superimposing the postoperative implant position onto the virtual pre-surgical implant plan using dedicated software. Descriptive and bivariate statistical analyses were performed.

Conditions

  • Maxillary Defect Reconstruction
  • Atrophic Edentulous Maxilla

Interventions

PROCEDURE

zygomatic implant installation using custamized bone supported surgical guide

Zygomatic implant placement using a customized bone-supported surgical guide. Indications included: * Severe posterior maxillary bone deficiency preventing placement of conventional implants * Post-surgical maxillary defects with limited options for bone reconstruction due to inadequate soft tissue coverage * Failure of previous reconstructive procedures
