Restoring teeth following crown lengthening procedures.

Crown lengthening procedures are often necessary to successfully restore teeth that have been mutilated at or below the level of the bone crest. Forced eruption is preferred to surgical removal of supporting alveolar bone, since forced eruption preserves the biologic width, maintains esthetics, and at the same time exposes sound tooth structure for the placement of restorative margins. To properly construct a crown, the minimal distance from the alveolar crest to the coronal extent of sound tooth structure should be 4 mm. Before initiation of forced eruption, the restorability of the root after completion of the orthodontic phase must be considered. A technique is suggested to calculate the root-to-crown ratio that will be created after root extrusion with respect to the coronal level of sound tooth structure before treatment.

A controlled putty-wash impression technique.

A precise impression is imperative for the construction of an accurately fitting indirect cast restoration. The putty-wash technique is commonly used in making impressions with silicone elastomers. Errors in manipulation may lead to inaccurate impressions. A technique is presented ensuring exact reseating of the putty impression tray and creation of a uniform wash space, which are essential for accurate results.

Diagnostic casts--an additional dimension.

The indications and usefulness of diagnostic casts are well documented in the literature. A method is presented that enables increased access to the lingual aspect of the casts by sectioning them in a midsagittal plane. The sectioned portions are held together in maximum intercuspation by acrylic keys. The interdigitated casts can thus be examined from all aspects, thereby deriving maximum benefit from them.

Prevalence of Candida albicans in denture wearers in an Israeli geriatric hospital.

Thirty-seven patients wearing complete dentures were investigated for Candida albicans. Twenty-five of the patients suffered from denture stomatitis and twelve had clinically normal mucosa. Candida albicans was isolated and identified from Sabouraud dextrose agar culture medium models constructed from impressions of the maxilla and from the upper dentures. The presence of Candida albicans was demonstrated in all denture wearers suffering from denture stomatitis and in 82% of denture wearers in a control group. A higher concentration of Candida was found in the denture stomatitis group. Large quantities of Candida resided in the denture base and not in the palate. Candida was also found in the denture base in areas not related to the lesion. The concentration of Candida was related to denture cleanliness.

Severe infraclusion ankylosis: report of three cases.

Tooth ankylosis may occur at any time during eruption and may show varying degrees of infraclusion. Cases of fully erupted teeth subsequently becoming totally embedded in bone are rare. The three reports described here show cases of severe infraclusion ankylosis; the etiology and related problems are discussed. Associated periodontal, prosthetic and orthodontic problems can be avoided with early diagnosis and treatment.
