6. Periodontal treatment decision tree

7. Periodontal Treatment Phase Phase I  Nonsurgical phase Directed to the elimination of the etiologic factors of dental, gingival, and periodontal diseases Phase II  Surgical Phase Phase III  Restorative Phase Phase IV  Maintenance Phase Immediately after completion of Phase I therapy, the patient should be placed on the maintenance phase (Phase IV) to preserve the results obtained and prevent any further deterioration and recurrence of disease.

8. Initial Disease Control Therapy (Phase 1)

9. Initial Disease Control Therapy (Phase 1) Scaling and Root Planning One of the most important services rendered to the patient is the removal of calculus and plaque deposits from the coronal and root surfaces of the teeth. Without meticulous removal of calculus, plaque, and toxic material in the cementum, other forms of periodontal therapy cannot be successful Elimination of Local Irritating Factors Other Than Calculus Overhanging restoration margins and open contacts that allow food impaction should be corrected before definitive prosthetic treatment is begun Temporary or permanent restorations of carious lesions depending on their prognosis

16. Gingival Level and Contour

17. Edentulous Area Prosthesis component: pontic and connector  influence the esthetics and durability of the prosthesis, as well as the health of the soft tissue . Biologically, a pontic must have a design that minimizes inflammation and permits oral hygiene procedures to be performed easily. Pontics should exhibit pressure-free contact on keratinized attached tissue and should not allow accumulation of food or prevent plaque control. This was assumed to prevent tissue inflammation and ulceration A ssessment of the location, height, width and contour of the residual ridge and the span of the edentulous area.

18. Magnitude of periodontal support Evaluation of the magnitude of periodontal support is relevant for patients who have a history of periodontitis, which can manifest clinically as an increase in the crown-to-root ratio and/or loss of teeth Ideal crown-to-root ratio  1:2 Another factor contributing to periodontal support is the number of abutment teeth , which is particularly relevant when considering a multi-unit fixed dental prosthesis

19. Abutment Tooth Preparation However, the most critical feature of the periodontic and prosthodontic relationship is the preparation margin. In general, margin quality is considered a critical feature for determining the acceptability of a fixed prosthesis. Having a minimal marginal opening is important to reduce the exposed cement line and subsequent leakage (62) that will result in penetration and adherence of bacteria and, eventually, the development of caries and gingival inflammation

20. Prosthesis Morphology

21. Prosthesis Material Most patients prefer their prostheses to look as natural as possible, but this should not take priority over prognostic factors such as remaining tooth structure, function, interocclusal space and other occlusal considerations. Choice of material will be a major contributing factor to the extent of tooth preparation necessary for the proposed prosthesis.
