Mouth preparation for removable partial denture

1. Mouth preparation for removable partial denture

2. Introduction Mouth preparation for partial dentures follow in logical sequence after oral diagnosis and treatment planning. The preparation of the mouth is fundamental to a successful removable partial denture service.

3. The extent of mouth preparation & the various procedures involved varies from person to person. However a majority of the patients might require extensive treatment .

4. It includes correction of occlusal plane, correction of occlusion, oral surgical preparation Periodontal preparation Orthodontic treatment Preparation of abutment teeth should be complete before working impressions are obtained.

5. Objectives of mouth preparation in removable partial denture 1.To establish a state of health in the supporting & contiguous tissues.   2.To eliminate interferences or obstructions to the placement, removal, & function of the prosthesis. 3.To establish an acceptable occlusal plane. 4.To alter natural tooth form to accommodate the requirements of form & function of the prosthesis.

6. Planning the mouth preparations When an RPD is identified as the preferred choice of treatment, an orderly, sequential plan of action should be thought of.The plan of action should include;

7. 1.A thorough examination of the patient including , Patient’s medical & dental history:

8. 2.Digital & visual examination: Tissues intolerant to stress, caries, Erosion, Abrasion, Loose teeth, Inflamed hypertrophic or ulcerated mucosa, Knifedge or unhealed ridges, & tori .

9. 3.Radiographs of teeth & edentulous spaces:

10. 4.Surveyed & occluded study casts.:

11. Mouth Preparation • Relief of pain • Extractions • Hyperplastic tissue • Muscle attachment & Frena • Bony spines &Knife-edge ridges • Hyperkeratoses, erythroplasia, & ulcerations • Dentofacial deformity

12. Periodontal preparation The periodontal preparation follows any oral surgical procedure. The objective of periodontal therapy is to return the health of the supporting structures of the teeth, creating an environment in which the periodontium may be maintained.

13. Periodontal treatment planning can be usually divided into 3 phases.   The first phase is considered disease control or initial therapy because the objective is to essentially eliminate or reduce local etiological factors before any periodontal surgical procedures are accomplished.It includes • Oral hygiene instruction, • Scaling & root planning & polishing, • Occlusal adjustment, & • Temporary splinting if indicated.

14. Oral hygiene instruction

15. Scaling & root planning

16. During the 2nd or periodontal- surgical phase any needed periodontal surgery is accomplished. This will need referral of the patient to a Periodontist.

17. The 3rd phase is the maintenance of periodontal health. Reinforcement of plaque control measures Debridement of all root surfaces of supragingival & sub gingival calculus & plaque .

18. Provision of support for weakened teeth:

19. Mobility caused by occlusal interference also may disappear after selective grinding.
