Anterior tooth replacement with implants in grafted alveolar cleft sites: a case series.

When a residual edentulous space in the anterior region remains after surgical and orthodontic treatment of alveolar cleft patients, implant placement with or without additional grafting is a treatment option. We placed a total of 10 implants in nine consecutive alveolar cleft patients (five females, four males) with residual anterior edentulous spaces and non-restored neighbouring teeth. Patient age generally varied from 18 to 22 years. Additional (tertiary) bone grafting, implant placement after 3 months of graft consolidation and implant uncover after no less than 6 months was the favoured surgical protocol in the five most recent cases. Ample time was allowed to evaluate and guide the development of soft tissues, following second-stage surgery. For this purpose, temporary crowns were fabricated, adjusted and left in place for over 3-4 months in seven out of nine cases. No implants were lost after a mean observation period of 3.4 years and all implants function without objective (radiographic) or subjective problems. Aesthetics were considered acceptable in seven out of nine cases. Unsatisfactory aesthetic results originated from poor implant positioning or alignment in two patients who did not undergo tertiary bone grafting. We conclude that implant placement in alveolar cleft sites is a comprehensive but viable treatment option. Tertiary grafting of the site is recommended to achieve better ridge contour and bone height. This allows optimal implant placement and alignment.

A review of temporary crowns and bridges.

Successful crown and bridgework relies heavily upon the precise use of temporary restorations. It is the importance of this stage in crown and bridgework, perhaps more than any other, that is so often underestimated. This article reviews the materials currently available for temporary restorations and assesses the various methods of construction.

The use of a self-polymerizing resin with enamel etchant for temporary stabilization.

The indications and characteristics of ideal temporary splints have been discussed. A technique has been presented using a self-polymerizing resin with an enamel etchant for extracoronal splinting of anterior teeth. When properly fabricated, the restoration has most of the properties of an ideal temporary splint: economy, simplicity of fabrication, lack of irritation, compactness, durability and esthetics.

Degradation of the sealing properties of a zinc oxide-calcium sulfate-based temporary filling material by entrapped cotton fibers.

During root canal therapy cotton may be placed in the pulp chamber before placement of a temporary filling. This study evaluated the effect on the sealing of a zinc oxide-calcium sulfate-based temporary filling material when fibers of the internal cotton passed through the filling material and reached the external surface of the temporary filling. Glass tubes were filled with a 3.5 mm thickness of the temporary filling incorporating a bundle of cotton fibers that passed from the inner surface of the restoration to the outer surface. The time for methylene blue stain to penetrate the filling was compared among four groups. Group 1 (large bundles of fibers) had 20 to 40 fibers, group 2 (medium bundles) had 10 to 15 fibers, group 3 (small bundles) had 3 to 5 fibers, and group 4 (negative controls) had no cotton fibers. All samples with cotton fibers leaked within 12 min. None of the negative controls leaked within the 21 -day observation time. These results demonstrate that even a very small amount of cotton trapped between the wall of the tube and the filling material dramatically reduced the sealing quality of the temporary restoration.
