Dentures and Dental Implants in Treating Patients Undergoing Surgery for Mouth Cancer

2014-07-23 21:56:20 | BioPortfolio


RATIONALE: The use of dentures and dental implants may help maintain chewing and speaking ability following surgery to remove tumors in the mouth.

PURPOSE: Phase II trial to study the effectiveness of dentures and dental implants in maintaining the ability to chew and speak in patients undergoing surgery for mouth cancer.



- Determine whether conventional or implant supported dental prostheses and current surgical reconstructive procedures restore oral function and quality of life to pre-cancer surgery levels in patients with early oral cancer.

OUTLINE: Patients complete a series of objective and subjective functional tests, questionnaires, and baseline examinations. Within 1-5 days, patients undergo the composite resection, including reconstructive surgery for the mandibulectomy group. Patients in the maxillectomy group receive an immediate maxillary surgical obturator. Approximately 6 weeks after ablative surgery, some patients receive radiotherapy for 5-7 weeks.

Patients receive 2-4 implants at 12-16 weeks after completion of radiotherapy or 8-16 weeks after ablative surgery. Patients then receive conventional dentures at 4-22 weeks after implant surgery. Implants are exposed during 27-48 weeks after placement and abutments connected for fabricating dental prostheses. Approximately 8 weeks are needed to fabricate the implant supported prosthesis.

Patients complete quality of life and other questionnaires prior to and at 8-21 weeks after surgery, 16 weeks after conventional denture insertion, and then 16 weeks after implant supported prosthesis insertion.

Patients are followed every 6 months for at least 3 years.

PROJECTED ACCRUAL: A total of 62 patients (22 requiring maxillectomy and 40 requiring mandibulectomy) will be accrued for this study within 42 months.

Medical and Biotech [MESH] Definitions

Complications that affect patients during surgery. They may or may not be associated with the disease for which the surgery is done, or within the same surgical procedure.

A form of therapy that employs a coordinated and interdisciplinary approach for easing the suffering and improving the quality of life of those experiencing pain.

Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.

A measure of the quality of health care by assessment of unsuccessful results of management and procedures used in combating disease, in individual cases or series.

The application of industrial management practice to systematically maintain and improve organization-wide performance. Effectiveness and success are determined and assessed by quantitative quality measures.
