简要总结
Objectives to evaluate the oral health-related quality of life and patient satisfaction in completely edentulous patients, when restored by maxillary and mandibular fixed (screw-retained) or removable telescopic retained implant supported prosthesis. 19 patients were randomized to receive either a fixed or a removable maxillary and mandibular full arch implant prosthesis. They were then asked to answer the OHIP-14 and a patient satisfaction questionnaire at 2 weeks, 3, 6 and 12 months post-prosthetic insertion.
详细描述
Interventions
General operative procedures:
Once the eligibility criteria were fulfilled in a patient, new complete maxillary and mandibular dentures were fabricated for this patient to allow for prosthetically driven implant placement. 4 implants were placed interforaminally so that they were parallel to each other. If the patient had an existing satisfactory denture, that was delivered at least six months ago, it was evaluated for retention, fit, support, stability, occlusion and esthetics. New and old dentures were later used for constructing the scan appliances.
The patients were randomly assigned into two groups with an allocation ratio 1:1. Simple randomization was done by preparing sequentially-numbered, opaque, sealed envelopes, that contained two-times folded cards with the treatment group written inside. Accordingly, the patients were assigned either to group T (control treatment/ telescopic retained implant supported removable overdentures) or group S (test treatment/ screw retained implant supported fixed prosthesis).
The intervention arm : Engaging (Internal hex) cylindrical, plastic patterns (Octa plastic cylinder, multi unit abutment, Red, Dentis, Daegu -Korea) were used to construct the primary copings of the telescopic prosthesis.The finished primary copings were scanned using a lab scanner (Shera Echo-scan 7. Dental Wings, Montreal-Canada). This was necessary to design and to mill the wax pattern of the secondary copings using CAD/CAM technology (Dental Wings Software, Dental Wings, Montreal -Canada). Secondary coping was designed to properly fit to the primary coping. The framework was then tried in. At that time it was ready for its intra-oral luting to the secondary copings.

入选标准
- •Completely edentulous male patients with an age range from 40- 70 years.
- •Patients with a HbA1c equal to or less than 7
- •All patients should have normal maxillo-mandibular relationship (Angle class I).
- •Patients should have maxillary and mandibular ridges at least 7mm in width and 13 mm in height in the interforaminal areas and in the esthetic zones (premolar to premolar regions), respectively. This accommodated a pre-planned implant size of 3.7mm x 10 or 11mm.
- •The maxillary and mandibular ridges should be covered by keratinized attached mucosa at least 5mm in width.
- •An interarch space between the edentulous maxillary and mandibular ridges should not be less than 22 mm to accommodate the planned maxillary and mandibular implant-supported prostheses. This was confirmed by mounted diagnostic casts.
- •Patients who were cooperative and who were psychologically and mentally stable as revealed from the initial interview with the patients were considered eligible.
排除标准
- •Females were excluded on purpose to prevent failures associated with osteoporosis and to avoid gender variability which definitely affects the results of patient satisfaction and OHIP.
- •Patients requiring hard or, soft tissue grafting of the proposed implant sites.
- •Heavy smokers (more than 10 cigarettes / day) or patients with para-functional habits like clenching or bruxism were excluded. This was important to decrease the risk of implant failure.
- •Patients with temporo-mandibular joint disorders were considered ineligible because of the expected occlusal disturbances.
- •Patients with systemic disease that might contra-indicate implants placement or affect osseointegration e.g. uncontrolled diabetes.
- •Patients who took chemo-or radiotherapy or any drug that might counter-affect the healing process or the quality of bone.

questionnaire. The patient satisfaction questionnaire is composed of 14 questions concerned with esthetics, speech, mastication, operative and prosthetic procedures, incidence of complications, pre-operative instructions, total time interval, cost, operator, hygienic procedures, overall experience as well as the willingness to repeat or refer others for the procedure.
