Buccal fat pad versus palatal rotation scarf graft for soft tissue around zygomatic implants

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study compares two soft-tissue grafting methods used during placement of zygomatic implants in patients with severely atrophic edentulous maxillae. Participants receive zygomatic implants and either a buccal fat pad graft or a palatal rotation scarf graft, and clinicians track soft tissue volume, tissue stability, and wound dehiscence over follow-up. Outcomes for tissue augmentation, complication rates, and clinical predictability will be compared between the two techniques. The aim is to identify the more reliable graft approach to support long-term success of upper-arch implant rehabilitation in challenging anatomy.

Why it matters

Who can join: the full rules

Inclusion Criteria:

1. Patient of age 18 years or more, who can understand and sign an informed consent.
2. Patients with severely atrophic edentulous upper arch (Cawood \& Howell class IV, V, VI) that could not be restored by standard axial implants without augmentation.
3. Patients with severely atrophic edentulous upper arch (Bedrossian classification inadequate bone in zones II or III or all three zones) that could not be restored by standard axial implants without augmentation.
4. Good systemic health (ASA score I-II)
5. Highly motivated patients with good compliance to oral hygiene habits.

Exclusion Criteria:

1. Patients with cardiovascular disease or pulmonary disease or medical systemic condition that does not permit the surgical procedure under general anesthesia (ASA III, IV, V and VI).
2. Patients with conditions contraindicating implant placement (e.g.: radiation to the head and neck, intra-venous bisphosphonates, uncontrolled Diabetes mellitus).
3. Heavy smokers. (\> 20 cigarettes daily)
4. Patient with psychiatric problems, severe bruxism, or other parafunctional habits.
5. Acute maxillary sinus infection or untreated maxillary sinus cyst.
6. Malignancy or pathology in Maxilla or Zygoma.
