Study Arms (1)

patient with horizontally deficient ridge in ethetic maxilary zone need (GBR) and implant placement

OTHER

a group of patients with with horizontally deficient ridge in esthetic maxillary zone will undergo ridge augmentation with guided bone regeneration (GBR) technique using polymethylmethacrylate (PMMA) polymer as membrane.

Procedure: guided bone regeneration (GBR).

Interventions

guided bone regeneration (GBR) using polymethylmethacrylate (PMMA) polymer as membrane.

Also known as: implant installation 6 months after (GBR)
patient with horizontally deficient ridge in ethetic maxilary zone need (GBR) and implant placement

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Patients with edentulous area related to horizontally deficient aesthetic zone of maxilla.
  • Patients are physically healthy with no medical history of any systemic or local disease that would contraindicate ridge augmentation and/or implant surgery or complicate the healing process. (Severe liver or kidney disease, a history of head and neck radiotherapy, chemotherapy at the time of surgery, uncontrolled diabetes, active periodontal in the residual dentition, inflammatory or autoimmune disorders of the oral mucosa, poor oral hygiene, patient failure to cooperate, and any other disease condition contraindicating the oral surgery).
  • Non-smokers.
  • Free from temporomandibular joint disorders and abnormal oral habits such as bruxism.
  • The edentulous ridges were covered with optimal thickness of keratinized mucosa with no signs of inflammation, ulceration or scar tissue.
  • The occlusion shows sufficient inter-arch space for future prothesis.

You may not qualify if:

  • General contraindications to surgery.
  • Patients subjected to irradiation in the head and neck area less than 1 year before fixation.
  • Untreated periodontitis.
  • Poor oral hygiene.
  • Uncontrolled diabetes.
  • Pregnant or nursing.
  • Substance abuse.
  • Psychiatric problems or unrealistic expectations.
  • Severe bruxism or clenching.
  • Immunosuppressed or immunocompromised.
  • Treated or under treatment with intravenous amino-bisphosphonates.
  • Patients participating in other studies, if the present protocol could not be properly followed
