  • DIAGNOSIS AND TREATMENT PLANNING IN COMPLETELY EDENTULOUS ARCHES www.indiandentalacademy.com
  • INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • CONTENTS Introduction Definition Of Diagnosis & Treatment Planning General Introduction Of the Patient&Evaluation Diagnostic Procedures Clinical history taking Clinical examination—Intra oral -Extra oral Examination of existing dentures. www.indiandentalacademy.com
  • Specific Investigations— Radiographs. Diagnostic cast. Pre-extraction record. Other investigation for systemic disease . Treatment planning. Summary&Conclusion. References. www.indiandentalacademy.com
  • INTRODUCTION Diagnosis Comprises of evaluation of patients health with respect to his/her physical,mental&social health, and these diagnostic findings decide treatment plan. Treatment planning is the most important milestone which depends on the diagnosis.So accurate diagnosis plays a very important role in ensuring predictable results of the treatment.prognosis depends on both diagnosis and treatment planning. www.indiandentalacademy.com
  • Definition of diagnosis & treatment planning GPT— • • Diagnosis is defind as determination of nature of disease. • Treatment planning is defind as the sequence of procedures planned for the treatment of a patient after diagnosis • Boucher –diagnosis consists of planned observation to determine & evaluate the existing conditions, which lead to decision making based on the condition observed. • Treatment plans should be developed to best serve the needs of each individual patient. www.indiandentalacademy.com
  • Winkler— Defines diagnosis is the examination of physical status, evaluation of mental or psychological make up, &understanding of needs of each pt to ensure a predictable result. Treatment planning means developing sequence of procedures planned for the treatment of a patient after diagnosis. www.indiandentalacademy.com
  • General introduction of the patient & Evaluation The first appointment imp for the development of mutual understanding, trust b/n pt dentist. Pt should be addressed by name Dentist should verify the personnel information collected by the receptionist. Patient Evaluation— Observation of the patients motor skills,level of coordination steadiness while walking. Unusual gait –Parkinson`s disease, neurological disorder, disease of the joint. . www.indiandentalacademy.com
  • EVALUATION OF MENTAL ATTITUDE The successful prosthodontic treatment depends on both technical skill &p mgt according to mental attitude. Neurosis– chr. Anxiety state at phy .State --increases alters neuromuscular co ordination. Dr. M .M. House cl of mental attitudes 1. Philosophical-ideal, co-operative, optimistic .Prognosis good. 2. Indifferent- least concerned about their oral health not co-operative, avoid treatment. Prognosis poor. 3. Critical-not satisfied with previous dentures &dentist. 4. Skeptical—poor gen health, unfavorable biomechanical condition,pessimistic. Pt motivation & education. 5. Hysterical-poor health, nervous, unrealistic expectation, poor prognosis education & motivation. www.indiandentalacademy.com

  • www.indiandentalacademy.com
  • RIDGE PARALLELISM Refers to relative parallelism between planes of the ridge. Class I-Both ridges are parallel to occlusal plane.

  • INTER ARCH SPACE Normally 16-20mm adequate for the accommodation of artificial teeth. Excessive inter arch space –increased resorption. -Poor stability. Inadequate space www.indiandentalacademy.com
  • www.indiandentalacademy.com
  • SAGITTAL PROFILE OF RESIDUAL ALVEOLAR RIDGE It is important to locate from where the mandibular ridge slopes up towards retromolar pad & ramus because occlusal contacts immediately above the the incline at the back part of the residual alveolar ridge will cause denture to slide forward. www.indiandentalacademy.com
  • BONY UNDERCUTS The bony undercuts do not play any role in retention of the denture. Bony irregularities – presence of sharp bony spicules , rounded smooth elevations. Retained root pieces. www.indiandentalacademy.com

Tongue size can be ---Hypertrophic. __Atrophic. __Normal. Tongue position:Wrights classified as ClassI—the tongue lies in the floor of the mouth with tip forward &slightly below the incisal edgsse of mandibular anterior teeth. ClassII—The tongue flattened & broadened but tip is a normal position. Class III-retracted depressed into floor of mouth with the tip www.indiandentalacademy.com curled upward into the body of the tongue.
  • Class I position is ideal with floor of mouth at an adequate height , so lingual border contacts it & maintains the seal. In class II &III floor of the mouth is low. www.indiandentalacademy.com
