Marginal Adaptation of Zirconium Dioxide Core according to the Abutment Teeth

Samples of low-nickel Zircaloy-2 (material MLI-788-see(1)), when anodically polarized in neutral 5 wt% NaCl solutions, were found to be susceptible to pitting and stress corrosion cracking. The SEM revealed that pitting of stressed samples was occurring below a 2000Å thick surface film which behaved differently from normal zirconium dioxide in that it did not display interference colours. Since the initial film thickness was approximately 65Å, attempts were made to examine the product film by transmission electron microscopy to deduce composition and how the corrosion environment could penetrate the continuous layer.

Unrealistic Expectations

Aim: The aim of this report is to describe the management of a prosthodontic patient expressing unrealistic expectations with respect to the transition to edentulousness. Objectives: To outline (1) the diagnosis and explicit expectations of the patient on presentation (2) considerations made during treatment planning to address the wishes of the first time prosthodontic patient (3) a sequential treatment plan utilizing transitional partial removable dentures to manage the change to edentulousness (4) functional and aesthetic result achieved. Results: Delivery of immediate removable partial dentures retaining key abutment teeth in upper and lower arches was a viable prosthodontic solution in the transition to edentulousness of a patient expecting unrealistic treatment outcomes. Conclusions: Addressing impractical expectations and devising a treatment plan amenable to both clinician and patient is difficult. Strategies to manage these wishes in prosthodontic dentistry can include transitional partial dentures. Clinical relevance: Practitioners who encounter similar situations may consider this report valuable.

Crown Preparation

Background: Telescopic double crown restoration can be used as an alternative treatment if the patient wants the tooth to be maintained as long as the supporting tooth has a healthy periodontal. In dental preparation telescopic double crown support requires a preparation guide so that the preparation can be acurate. Minimal preparation can cause the results of the telescopic double crown restoration to be overcontoured, so that the patient may occur uncomfortable, speech disorders and esthetic is not good. Objective: to provide information about the importance teeth preparation guidelines for prosthodontic treatment with telescopic double crown restorations. Case: A 72-year-old female patient, coming to the dentist wants to make dentures so that she can chew food well and improve her appearance. The remaining teeth are only 13 and 23. In making the denture, the patient wants the teeth to be retained (not removed) and the denture is aesthetically good. Case Management: Make a diagnostic wax-up on a semiadjustable articulator to estimate the results of restoration, mould the patient's teeth before starting the preparation with three times putty for the preparation guide and making a temporary crown. the first putty mold is cut mesial-distal right in the middle of the incical teeth, the second putty mould is cut in the labial-palatal direction right in the middle of the tooth mould, the third putty mould is fixed on the stock tray to make the temporary crown. Preparation of teeth 13 and 23 with regard to the putty cut preparation guide, then moulding the maxilla and mandibula with double impressions using an individual tray, after that make the temporary crown directly with the third putty mould. Conclusion: The preparation guide of teeth is very necessary so that the making of telescopic double crown restorations is not overcontoured, so that esthetic and retention can be achieved which are good and do not cause speech disorders.Keywords: Telescopic double crown, tooth preparation guide, estheticCorrespondence: Anindita Apsari.
