Prosthetic exam appointment not available 1.IHS treatment policy outlines prosthetics are low on priority list. 2. Patients cancel or break appointments without notice. 3.Prosthetic exams scheduled only on specific week-days. 1. extractions, restorations, emergencies are scheduled before prosthetic appointments. 2. cancelled and broken appointments impede potential prosthetic appointments. 3. Patient unavailable for a prosthetic appoint on a specific week day. 1 1 5 5 1. Recruit Dentists, maintain volunteer Dentists participation. 2. Patient education regarding value of keeping multiple appointment sequence in prosthetic treatment. 3. Revise schedule; allow for exam-prosthetic appointments to be available all clinic da

Patient unable to be appointed for restorative needs (prior to prosthetic fabrication) 1.Dentist shortage 2. Existing schedule is filled with Level I,II, and III appointments. 1.Prosthetic fabrication is delayed an unacceptable length of time. 2. Negative affects upon nutrition, speech, and self-esteem. 1 1 5 5 1. Continue to recruit Dentists. 2. Continue volunteer Dentists/ Student Dentists programs.
