This prospective case series is designed to evaluate the effect of autologous bone marrow aspirate concentrate applied around zygomatic implants placed via the intrasinus approach. The study will include adult patients with severe maxillary atrophy requiring zygomatic implant rehabilitation. BMAC will be prepared from iliac crest aspirate and loaded on gelatin sponge at the implant site. Peri-implant bone density will be assessed using CBCT at baseline and 6 months postoperatively. Secondary implant stability will be measured using resonance frequency analysis. (Recruitment has not started yet)

Bone density around zygomatic implants
Bone density measured using Cone Beam Computed Tomography (CBCT) and expressed in Hounsfield Units (HU)
6 months postoperatively
secondary stability of zygomatic implants
6 months postoperatively
All eligible participants with atrophied maxilla receiving zygomatic implant placement for fixed prosthetic rehabilitation.
placement of zygomatic implants via the intrasinus approach in the posterior maxilla of patients with severely atrophied maxilla. Bone marrow aspirate concentrate prepared by double centrifugation of bone marrow aspirated from anterior iliac crest of the patient then loaded on gelatine sponge and applied around the zygomatic implants. Conventional implants may be placed in the anterior maxilla. Procedure performed under general anaesthesia with propofol induction and sevoflurane maintenance.
