Immediate aesthetic provisionalization for the dental implant patient.

Providing an acceptable provisional restoration for the patient undergoing tooth extraction in conjunction with bone grafting and dental implant treatment can present a challenge for the restorative dentist. The unnatural appearance and function of the typical temporary is often unacceptable to the patient whose treatment requires long-term temporization. This article describes a technique for using heat-cured acrylics to provide immediate aesthetics in a provisional bridge for such patients.

[The importance of apical and coronal leakage in the success or failure of endodontic treatment].

The present paper reviews the literature and gives the evidence that apical and coronal leakage of the root canals may lead to failures of the root-canal therapy. It becomes clear that none of the present-day root canal sealers may hermetically seal "the root canal wall--gutta-percha filling interface". In this respect the importance of perfectly sealing coronal restorations (both temporary and permanent) is emphasized.

Long-term esthetic provisional restorations in dentistry.

The role of interim dental restorations used for indirect restorative and prosthodontic procedures has changed dramatically in the past several years. These restorations are no longer regarded as temporary restorations but rather as provisional restorations with distinct functions and purposes. Provisional restorations have become a vital diagnostic and assessment tool to evaluate function color, shape, contour, occlusion, periodontal response, implant healing, and overall esthetics. An accurate fit and margination is essential to insure and maintain pulpal health of the tooth. With increased demands being placed on provisional restorations, new materials and techniques are being developed and some existing protocols are being refined to accomplish the desired goals. Provisional restorations are often in the oral environment for several months, requiring a well-fabricated and stable restoration. This review is designed to report on current materials, techniques, and concepts in fabricating and maintaining long-term esthetic provisionals.

The use of amalgam powder and calcium hydroxide to recreate a radiopaque image of a lost dental restoration.

Radiographs of dental restorations are highly reliable when used to identify postmortem dental remains. A problem exists if key dental restorations are missing or defective, which results in the loss of a comparative radiographic image. This article describes a simple method allowing the odontologist to quickly recreate a temporary radiopaque restoration. This article presents a method of using amalgam powder (radiopaque material) and calcium hydroxide (radiopaque material and transport medium for the amalgam powder) to recreate a radiopaque image on a tooth that has lost a dental restoration. Amalgam powder and calcium hydroxide is easily obtained (in any dental office), fairly clean, easy to manipulate, inexpensive, inert, stable, and able to be removed without damaging the dental remains. The amalgam powder/calcium hydroxide mixture can easily be re-shaped or modified to reflect the radiopaque image of the original restoration. Radiographic comparison of the "restored" dental remains to the antemortem radiographs is now possible. The use of this technique is presented in a case report.

Monkey pulpal responses to conventional and adhesive luting cements.

Monkey pulpal responses to metal inlays luted with a combination of an adhesive resin and luting composite and conventional dental cements were histopathologically evaluated. Initial pulpal responses caused by re-exposure of the cut dentin surfaces and luting procedure under hydraulic pressure subsided at 90 days after final cementation. There was no significant difference among pulpal reactions to conventional dental cements and a combination of an adhesive resin and luting composite. The adhesive resin coating of freshly cut dentinal walls/floors immediately after cavity preparation seems to provide protection for the dentin and pulp in indirect restorations requiring temporary sealing.

Placement of implants into fresh extraction sites: 4 to 7 years retrospective evaluation of 95 immediate implants.

A 7-year follow-up of implants placed immediately after tooth extraction into fresh extraction sites is reported. Small autogenous bone chips (from bone adjacent to implant sites) were grafted into the defect between the implant and the socket walls when needed. Closure of the wound was obtained by coronal repositioning of the flap, and no membranes were used. Care was taken to minimize hematoma formation under the flap during healing by part-time use of removable prosthesis with thick soft linings after implant surgery. At second stage surgery, mucoperiosteal flaps were apically repositioned for maximum attached gingival width and to reconstruct the vestibule. Minor complications such as exposure occurred in 16% of cases. Implant mean 5-year cumulative survival rate was 95%. There was no implant loss after loading. The results indicated that implants placed into fresh extraction sites grafted with autogenous bone chips will heal predictably.

[Public school programme for fissure sealants and its effect on the private demand for restorative dentistry for temporary teeth].

OBJECTIVE: To analyse the effect of a public school odontological programme of fissure sealants on the private demand for restorative dentistry for temporary teeth. DESIGN: A longitudinal, comparative study was conducted. It had 2 groups, control and sealant, with 3 years monitoring. SETTING: Santa Fe Health Area, concretely in the local districts (LD) of Santa Fe and Pinos Puente, Granada, Spain, starting in the school year 1996/1997. PARTICIPANTS: The sealant group was selected from the Santa Fe LD (which had a public programme of fissure sealants) (n=129); and the control group (n=120), from Pinos Puente LD. INTERVENTIONS: All the school students were examined (+ report issued) in the schools every 6 months for 3 years. The sealant group children received at the health centre fissure sealants in their first permanent molars. MAIN MEASUREMENTS: The restorations performed in temporary teeth for both groups were analysed (x+/-EE) during the study at 12, 24, and 36 month follow-up. RESULTS. The sealant group had a significantly greater increase in restorative treatment for temporary teeth (P< .05) than the Control group at all monitoring points. CONCLUSIONS: A public programme of fissure sealants raised private restorative treatment for temporary teeth.

The perio-aesthetic-restorative approach for anterior reconstruction--Part I: Evaluation and periodontal surgery.

Precise communication is critical to the delivery of functional and aesthetic restorations. Interdisciplinary therapy integrates individual disciplines to function as a comprehensive unit and consistently provide predictable treatment results. Thorough diagnosis and treatment planning must be executed between every member of the perio-aesthetic-restorative team to ensure accurate communication and provision of the patient's desires. This two-part article compares the multidisciplinary treatment approach with the interdisciplinary approach in the replacement of congenitally missing lateral incisors.

The use of transitional implants for immediate fixed temporary prostheses in cases of implant restorations.

While the original Brånemark implant protocol has continued to evolve, the avoidance of implant loading during osseointegration remains a prerequisite with all implant systems. Immediately loaded transitional implants have recently been developed to support the fabrication of a fixed provisional prosthesis that provides implant patients with improved aesthetics and function during the osseointegration period. In this manner, osseointegration can occur free from prosthetic and transmucosal loads. This article describes the use of transitional implants and presents a classification of three different case types.

Flexural properties of acrylic resin polymers reinforced with unidirectional and woven glass fibers.

STATEMENT OF PROBLEM: Fiber-reinforced plastics for dental applications have been under development for some time. A major difficulty in using reinforcing fibers with multiphase acrylic resins, such as powderliquid resins, has been improper impregnation of fibers with the resin. PURPOSE: The aim of this study was to describe and test a novel system to use polymer-preimpregnated reinforcing fibers with commonly used multiphase acrylic resins. MATERIAL AND METHODS: Continuous unidirectional and woven preimpregnated glass fiber reinforcements (Stick and Stick Net) were used to reinforce heat-curing denture base and autopolymerizing denture base polymers. A temporary fixed partial denture polymer was also reinforced with Stick reinforcement material. Five test specimens were fabricated for unreinforced control groups and for Stick- and Stick Net-reinforced groups. A 3-point loading test was used to measure transverse strength and flexural modulus of the materials and ultimate strain at fracture was calculated. Cross-sections of test specimens were examined with a SEM to evaluate degree of impregnation of fibers with polymer matrix. Quantity of fibers in test specimens was determined by combustion analysis. RESULTS: Transverse strength of heat-curing denture base polymer was 76 MPa, Stick reinforcement increased it to 341 MPa, and flexural modulus increased from 2550 to 19086 MPa. Stick Net reinforcement increased transverse strength of heat-curing denture base polymer to 99 MPa and flexural modulus to 3530 MPa. Transverse strength of autopolymerizing denture base polymer was 71 MPa; Stick increased it to 466 MPa; and flexural modulus increased from 2418 to 16749 MPa. Stick Net increased the transverse strength of autopolymerizing denture base polymer to 96 MPa and flexural modulus to 3573 MPa. Transverse strength of temporary fixed partial denture polymer increased from 58 to 241 MPa and flexural modulus from 1711 to 7227 MPa. ANOVA showed that reinforcement type and polymer brand affected transverse strength and modulus (P <.001). Stick Net reinforcement increased the strain at fracture, whereas Stick reinforcement decreased the strain values. SEM examination revealed well-impregnated glass fibers with polymer matrix. Quantity of glass fibers varied from 6 to 28 vol-%, the lowest being with Stick Net reinforcement and the highest with Stick reinforcement. CONCLUSIONS: Novel glass fiber reinforcements may considerably enhance flexural properties of multiphase dental polymers, which is due to proper impregnation of fibers with polymer matrix. By using Stick or Stick Net reinforcement, the strain at fracture of the material can be modified.

Flexible casts used in making indirect interim restorations.

This article describes a procedure for making indirect interim restorations from a cast and dies made of polyvinyl siloxane impression material. The use of these flexible casts and dies facilitates the removal of the polymerized resin from the cast and the rapid set of the polyvinyl materials reduces the time involved in making the indirect interim restorations.
