Titanium, as an implant material, is regarded to be durable and biocompatible, which allows functional replacement of missing teeth. A Cox proportional hazards regression model showed that initial probing depth, initial furcation involvement, initial mobility, initial percent bone loss, presence of a parafunctional habit without a biteguard, and smoking were all associated with an increased risk of tooth loss. Prognosis can be divided into overall prognosis and individual tooth prognosis. In the era of evidence-based dentistry, outcome studies ... • Age. Individual tooth prognosis. questionable possibility for adequate restoration of the clinical crown) had to be taken into account. Considerable emphasis was placed on improving occlusal function. Your dentist may loosen the tooth in the gum using a tooth removal instrument called an elevator. A prospective study of the factors affecting outcomes of non‐surgical root canal treatment: part 2: tooth survival. The data indicate that the absence of clinical inflammation and a stable periodontium (eg, no increasing probing depths, no additional loss of bone, or clinical attachment) are advantageous for retaining teeth. III. Dr. Sebastien Dujardin maintains a private practice in periodontics in Lille, France. The searches focused on publications that contained clinical data regarding success/failure/complications. dentistry. Doyle SL, Hodges JS, Pesun I, Baisden MK, Bowles WR. A random effects model showed weighted mean survival rates of 85.6% (95% confidence interval [CI], 76.7–91.5) for CR and RR procedures OVERALL. The area of each lesion was measured before treatment and 1 to 12 years after completion of the endodontic treatment. Within each type of prosthesis, raw data were combined from multiple studies and mean values calculated to determine what trends were noted in the studies. The 1st statement is false and the second statement is true. Teeth such as the maxillary premolars, which have pronounced root concavities, are also more difficult to instrument and maintain, and likewise have a worse prognosis than teeth with relatively straight roots.8, • Tooth mobility. Patients were examined and their dental records were reviewed. Materials and methods: Increased probing depth, more severe furcation involvement, greater mobility, unsatisfactory crown-to-root ratio, malpositioned teeth, and teeth used as fixed abutments resulted in worse initial prognoses. Individuals who smoke more than 10 cigarettes per day have an increased risk of more severe periodontal disease, a less predictable response to initial therapy and a more complicated therapeutic response. Dental implants, however, present a de novo situation and a functional period of at least 5 years is often required before peri-implant diseases are established and detected. Factors that may influence the overall prognosis include patient age, current severity of disease, systemic factors, smoking, the presence of plaque, calculus and other local factors, patient … In most cases of patients' requesting extractions, the ethical principle of nonmaleficence will play a decisive role in the dentist's decision making. • Crown-root ratio. The time of implant loss (preprosthetic vs postprosthetic) varied with type of prosthesis. Evaluation of prognostic factors affecting root coverage in patients before planned orthodontic treatment . Full size table. Judicious, strategic extractions may permit the placement of long implants in ideal positions. Clinicians interpret clinical data quite differently in their advice of surgery when practice guidelines are not provided, as the results showed high variation in surgical recommendation. Eighty-four per cent of the failures occurred after 5 years. Dr. David L. Hoexter is a clinical professor of periodontology and implantology at Temple University School of Dentistry, Philadelphia, and editor in chief of the Dental Tribune U.S. Other factors, such as the strategic value of a tooth and financial limitations in relation to long-term prognosis… An understanding of the patient's needs and the length and likely success of treatment guides the decision of whether to preserve teeth or extract them and place implants. 2008). Following a complete evaluation of the patient, treatment planning requires the analysis of individual teeth, accurate diagnosis, and prognosis evaluation. Of 2,139 teeth that originally had been considered of questionable prognosis, 666 were lost. Breast cancer staging. Clinicians linked to a training center shared a common treatment philosophy as to when periodontal surgery should be performed. The sum of these scores became the score for that tooth. Data were submitted the weighted least-squared analysis. A total of 1,201 prostheses were incorporated within 48 hours after the surgery. Factors that need to be considered when deciding on an overall periodontal prognosis include the following. Initial and long-term marginal bone changes were identified. utilization of tooth as an abutment for removable or fixed prosthesis, (iv) and tooth type (nonmolar teeth versus molar teeth). In the esthetic zone, before resective surgical procedures are used to resolve periodontitis, consideration should be given to the esthetic outcome. Prognosis of teeth in the line of mandibular fractures. Data from a longitudinal study of periodontal therapy for 78 patients over 8 years were analyzed with regard to effect of tooth types on treatment results. Finally, when the prognosis is “hopeless,” extraction is indicated. The results suggested that this population reflected many of the same characteristics seen in well-maintained patients. Non-controlled type 2 diabetes in a 42-year-old patient. Introduction The ideal restoration of endodontically treated This subgroup consisted of 42 patients (1,044 teeth) in maintenance care for 14 years; 16 tested IL-1 genotype-positive (IL-1GP). Determination of Prognosis Prof.Dr. Kalkwarf KL, Kaldahl WB, Patil KD, Evaluation of furcation region response to peri-odontal therapy. tooth implies understanding the biological and mechanical outcomes as multifactorial events over the individual’s life span. The 2013 longitudinal study by Tada et al56 about the prognostic factors affecting the survival period of abutment teeth of removable partial denture evaluated 147 patients provided with 236 new RPD (846 analyzed abutment), finding out that the survival rate of direct, indirect and no abutment teeth to 5 years was 86.6, 93.1 and 95.8% respectively. Diabetic patients have a higher prevalence of periodontal disease and greater attachment and bone loss.18,19 Patients with diabetes, especially poorly controlled diabetes, will generally have a worse overall prognosis than patients who are not diabetic (Fig. The major prosthetic complication was the fracture of the all-acrylic FDP. Of 1,464 teeth which originally had furcation involvements, 460 were lost, 240 of them by one-sixth of the patients who deteriorated most. The results of treatment were directly dependent on the preoperative status of the pulp and periapical tissues. Introduction J Periodontol 59(12): 794-804, 1988. Individual tooth prognosis: • determined after the overall prognosis and is affected by it. The decision to extract a tooth will fluctuate depending on its clinical condition, and this action should be supported by the literature, clinical experience, and the patient's declared goals. LASER, AO launches unique virtual member community, 2020 Greater New York Dental Meeting: Celebrating dentistry, Seeing is believing: iTero Element 5D Imaging System, Advances in diaphanization and photography reveal wonders of dental pulp chamber, A handpiece designed for root canal preparation and irrigation, Creation of gummy bone to improve osseous graft handling and healing by incorporation of PRP, Periodontist becomes one of first to use surgical robotics when placing implants, Extend your front desk with digital tools from Simplifeye, Are we playing “Russian Roulette” with our patients? This difference was not statistically significant. Tobacco/ smoking 4. Nine were smokers, and 30 had a history of smoking, with an average of 29.44 pack years. thus positively affect the long-term success. On the contrary, with multiple issues associated with endodontic therapy, minimal coronal tooth structure with decayed root dentine, and/or high caries index, which prohibits crown lengthening, replacement of the tooth with lower value may be prudent to avoid potential complications (Palmer & Howe 1999, ... Tooth loss in most cases is part of a therapeutic treatment plan wherein a clinician extracts a tooth due to acute oral disease (e.g., acute apical periodontitis) or chronic oral disease (e.g., periodontal support loss due to severe periodontitis and nonrestorable caries-affected teeth).
