Summary

The evolution of zygomatic implant techniques, from the original procedures to the Zygomatic Anatomy-Guided Approach (ZAGA), has significantly improved outcomes for patients with severe maxillary atrophy. Despite these advancements, challenges such as peri-implant tissue recession, sinus complications, and aesthetic concerns persist. Bone augmentation and soft tissue enhancement techniques, including sinus lifts, connective tissue grafts, and buccal fat pad utilization, have been employed to address these issues with varying degrees of success. However, the need for predictable and stable bone regeneration and soft tissue contouring remains critical for long-term implant success.

The following study aims to assess bone gain, soft tissue contour, and stability after using bone lamina shell, providing a potential solution to enhance peri-implant tissue integrity and optimize functional and aesthetic outcomes in zygomatic implant rehabilitation

Conditions

  • Zygomatic Implants

Interventions

PROCEDURE

Group A

after zygomatic implant placed with channel shape osteotomy,Wetting, trimming and fixation of xenogenic lamina shell buccal to placed zygomatic implants in combination with xenogenic particulate form to fill all gaps between lamina from one side and native bone and implant from other side

PROCEDURE

Group B

after zygomatic implant placed with channel shape osteotomy ,Blunt dissection to buccal space to extract buccal pad of fat which will be mobilized and advanced to cover buccal surface of zygomatic implants and fixed over it with either suturing to palatal mucosa or with bone tacs
