Supportive Periodontal Therapy (SPT) aims to maintain oral health and prevent the recurrence of periodontal disease through scheduled evaluations and treatments. It consists of goals such as minimizing periodontal disease progression, reducing tooth loss, and identifying other oral conditions, with varying treatment types based on patient needs. The document highlights the importance of compliance and tailored maintenance intervals for effective long-term management of periodontal health.
Supportive Periodontal Therapy
- 1. Supportive Periodontal Therapy Maintenance phase Recall/re-evaluation Supervised recall programme
- 2. Definition • Procedures performed at selected intervals to assist the periodontal patient in maintaining oral health. -GPT 2001. • Therapeutic measures to support the patient’s own efforts to control and to avoid re‐infection. - Jan Lindhe.
- 3. Correct sequence of treatment
- 4. Rationale for SPT 1. Limitation of mechanical subgingival debridement 2. Recolonization of pocket 3. Long JE (weak attachment) 4. Subgingival scaling alters the microflora of periodontal pockets 5. To prevent interception
- 5. Goals Of SPT • 3 main goals according to the AAP position paper (1998) 1. To prevent or minimize the recurrence and progression of periodontal disease in patients who have been previously treated for gingivitis, periodontitis and for peri-implantitis.
- 6. Goals Of SPT 2. To prevent or reduce the incidence of tooth loss by monitoring the dentition 3. To locate and treat other diseases or conditions found in the oral cavity in a timely manner
- 7. Objectives of SPT Periodontal • Preservation of bone support • Maintenance of stable CAL. • Reinforcement of proper home care. • Maintenance of a healthy and functional oral environment General • Assessment of the general health status • Encouragement of patients oral hygiene efforts • Continuation of patient education • Establishment of the future maintenance regime
- 8. Types of SPT • Schallhorn and Snider (1981) 1. Preventive maintenance therapy • Periodontally healthy individuals. 2. Trial maintenance therapy • Mild to moderate periodontitis 3. Compromised maintenance therapy • Medically compromised patients where active therapy is not possible. 4. Post-maintenance treatment therapy • maintenance for prevention of recurrence of disease
- 9. Maintenance Program (Carranza) SPT 1. Examination and Evaluation (14 mins.) 2. Maintenance Rx and oral hygiene reinforcement (36 mins.) 3. Report, Cleanup, and Scheduling (10 mins.)
- 10. Part- 1: Examination and Evaluation • Patient greeting • Medical history changes • Oral hygiene status • Gingival changes • Pocket depth changes • Mobility changes • Occlusal changes • Dental caries • Oral pathologic examination • Restorative, prosthetic, and implant status Examination of prosthesis/abutment components; Evaluation of implant stability; Occlusal examination; Other signs and symptoms of disease activity.
- 11. Radiographic Examination of Recall Patients Clinical caries and no high-risk factors for caries. Posterior bite-wing examination at 24 to 36-month intervals. Clinical caries or high-risk factors for caries Posterior bite-wing examination at 12 to 18-month intervals. History of periodontal treatment with disease under good control. Bite-wing examination every 24 to 36 months; full- mouth series every 5 years. Periodontal disease not under good control. Periapical and/or vertical bite-wing radiographs of problem areas every 12 to 24 months; full-mouth series every 3 to 5 years Root form dental implants Periapical or vertical bite-wing radiographs at 6, 12, and 36 months after prosthetic placement, then every 36 months unless clinical problems arise.
- 13. Part-2: Maintenance treatment and Oral hygiene reinforcement • Oral hygiene reinforcement • Scaling • Polishing • Chemical irrigation or site-specific antimicrobial placement
- 14. Part-3: Report, Cleanup, and Scheduling • Write report in chart. • Discuss report with patient. • Clean and disinfect operatory. • Schedule next recall visit. • Schedule further periodontal treatment. • Schedule or refer for restorative or prosthetic treatment.
- 15. Frequency of SPT • Ramfjord et al. (1993) For most patients with gingivitis but no previous attachment loss, supportive periodontal treatment twice a year. • For patients with a previous history of periodontitis, 3 months interval (less than 6 months) • Various clinical trails suggest- four times a year.

- 17. Classification of Post-treatment Patients (Merin)
- 20. Effectiveness of SPT (for patients with Gingivitis) • Axelsson and Lindhe (1974-1976): demonstrated that gingivitis could be prevented by regular professional cleaning in children aged 7 to 14 years. • Axelsson and Lindhe (1981): reduced caries and BOP • Badersten et al.(1990): Routine mechanical subgingival debridement of shallow bleeding sites at SPT visits results in attachment loss.
- 21. • Gingival conditions improved by 60% and tooth loss was reduced by about 50% (Lovdal et al. 1961) • The mean loss of probing attachment was only 0.08 mm per surface as opposed to 0.3 mm in the control group (Suomi et al. 1971).
- 22. Effectiveness of SPT (for patients with Periodontitis) • Nyman et al. (1977) reported on 25 patients for 2 years (No SPT) • Regular SPT at 3-4 times a year allows disease monitoring • Early detection and Rx Nyman et al. (1975) Test OHI and SPT 2 weeks Control OHI and SPT 6 months
- 23. • Dahlen et al. (1992) Professionally delivered supragingival toothcleaning, in combination with self-performed plaque control for 2-year period effectively change the quantity and the composition of the subgingival microbiota • Hellstrom et al. (1996) same protocol has a significant effect on the subgingival microbiota of moderate to deep periodontal pockets clinically.
- 24. • (Lindhe & Nyman 1984) • 75 patients with extremely advanced periodontitis, • recurrent infection occurred in only very few sites during a 14‐year period of effective SPT. • recurrent periodontitis was noted at completely unpredictable time intervals, in about 25% of the patient population (15 of 61)
- 25. 30‐years plaque‐control-based maintenance program • Axelsson et al. 2004 375 test and 180 control The test group- prophylactic visits every second month for the first 2 years and every 3–12 months (according to their individual needs) over 3–30 years very few teeth were lost (0.4–1.8) 1.2–2.1 new carious lesions (>80% secondary caries) 2–4% of all sites exhibited attachment loss of ≥2 mm.
- 26. Compliance affecting SPT • Wilson stated that “Patients who comply to suggested recall visits are periodontally healthy and keep their teeth longer.”
- 27. Improving compliance • Wilson suggests: • Counselling them about their condition, the role of treatment and the importance of compliance • Simplify instructions to patients • Teach them self performed plaque control • Acccommodating patient needs • Positive reinforcement
- 29. Maintenance of Implants • Lang et al. 2004, Cumulative Interceptive supportive Therapy
- 30. Maintenance intervals for implant patients 1. Patients with both teeth and implants should see the periodontist as often as necessary to keep the periodontium and peri-implant tissues healthy. 2. Totally edentulous patients with implants should be seen at least once per year.
- 31. Conclusion and recommendations • SPT should be based on profile of risk assessment • No scientific evidence for subgingival debridement of sites with BOP without concomitant increase in pocket depth. (it should better be avoided) • SPT minimizes the risk of periodontal disease progression and tooth mortality • In absence of long-term evaluation of SPT for dental implants, same principles of SPT that is used for periodontitis is also apropriate
- 32. Recommendation for research • Studies are needed: 1. to evaluate the efficacy of supragingival Rx alone as compared to subgingival debridement 2. To assess the value of antibiotics as adjunct and stand alone Rx during SPT 3. Patient based factors must be considered in analysis 4. Prospective and multicenter studies to findout efficacy of SPT
