Implant-supported telescopic restorations in maxillofacial prosthetics

Area of Science:

• Oral surgery
• Prosthodontics
• Oncology

Background:

• Oral cancer patients often receive radiation therapy, increasing risks for complications like osteoradionecrosis.
• Dental rehabilitation is crucial for function and quality of life post-treatment.
• Implant-supported prostheses are a common solution, but specific designs may mitigate radiation-related risks.

Purpose of the Study:

• To compare the efficacy and safety of two types of telescopic prostheses in partially irradiated oral cancer patients.
• To evaluate positional stability, peri-implant hygiene, function, and esthetics.
• To identify prostheses that minimize risks of soft tissue ulcers and osteoradionecrosis.

Main Methods:

• Eight partially irradiated oral cancer patients were enrolled.
• Participants received either mandibular implant and mucosa-supported telescopic coping prostheses or completely implant-supported telescopic prostheses.
• Outcomes assessed included positional stability, peri-implant hygiene, functional status, esthetics, and soft tissue health.

Main Results:

• Both prosthesis types demonstrated adequate positional stability and peri-implant hygiene.
• Both restorations led to functional and esthetic improvements for the patients.
• Completely implant-supported prostheses successfully avoided soft tissue ulcers, a known precursor to osteoradionecrosis.

Conclusions:

• Completely implant-supported telescopic prostheses are recommended for irradiated oral cancer patients.
• This design effectively prevents soft tissue complications associated with radiation therapy.
• This approach enhances patient outcomes by reducing the risk of osteoradionecrosis.
