Extraction, immediate-load implants, impressions and final restorations in two patient visits.

BACKGROUND: Since the advent of immediately loaded implants, patients have experienced shorter treatment times, reduced amount of surgical therapy, preserved gingival esthetics and the comfort and security of fixed prostheses. Practitioners have experienced less expense in the form of chair time and greater patient satisfaction. CASE DESCRIPTION: The authors present two cases in which, at the first clinical visit, they extracted maxillary incisors, placed hydroxyapatite-coated implants, took impressions for final restorations and stabilized the implants immediately with a fixed interim prosthesis. At the second clinical visit, the authors placed the final restorations. All of the implants were integrated clinically, and gingival esthetics appeared to have benefited from preservation of papillary form, which was made possible with fixed interim anterior restorations. The patients expressed satisfaction with the results particularly because the treatment was accomplished in two clinical visits. CLINICAL IMPLICATIONS: The cases presented demonstrate a technique that may be of value to therapists who place immediate-load implants. The long-term effectiveness of immediate-load implants requires further evidence to ensure their long-term usefulness and safety.

Success of an alternative for interim management of irreversible pulpitis.

BACKGROUND: Extraction and endodontic therapy are treatment options for irreversible pulpitis. Extraction often is chosen for financial reasons. The authors conducted a study to investigate an alternative interim therapy. METHODS: The authors recruited patients (N = 73) with irreversible pulpitis and whose teeth were restorable but who opted for extraction owing to financial reasons. After undergoing pulpotomy, the teeth were restored by random assignment with one of two intermediate restorative materials: Caulk IRM (Dentsply Caulk, Milford, Del.) (Group I, n = 38) or an IRM base with glass ionomer core (Fuji IX GP, GC America, Alsip, Ill.) (Group II, n = 35). The authors monitored the teeth over six and 12 months for pain, integrity of restoration and radiographic periapical status by densitometric analysis. RESULTS: By six months, 10 percent of subjects remaining in the study (Group I, n = 27; Group II, n = 25) reported pain; by 12 months, 22 percent (Group I, n = 22; Group II, n = 18) reported pain. A two-tailed Fisher exact test showed no significant difference (P > or = .05) between groups at either time interval. No apical radiographic change was noted in 49 percent of teeth at six months (Group I, n = 18; Group II, n = 19) and 42 percent at 12 months (Group I, n = 16; Group II, n = 15). Chi2 analysis demonstrated no significant differences (P > or = .05) between groups. Seven of 22 restorations in Group I and four of 18 in Group II required repair at 12 months with no statistical difference (chi2 analysis, P > or = .05). CONCLUSIONS: The interim treatment of eugenol pulpotomy using either restorative material reliably prevented pain for six months. For longer periods, both restorations may require repair. CLINICAL IMPLICATIONS: This option should preserve the integrity of the arch and extend the use of the tooth while the patient finds the means to finance complete endodontic treatment.

Mini-dental implant insertion with the auto-advance technique for ongoing applications.

The clinical and histological results of two cases demonstrating retrieved Sendax mini-dental implants in two different patients is the focus of this report. The mini-dental implants were inserted using the auto-advance technique and loaded immediately. The implants were retrieved at 4 months following insertion and at 5 months following insertion and were prepared and reviewed histologically. Clinically, the implants had no mobility, with no apparent exudate or bleeding upon probing, prior to removal. At the time explant procedures were performed, the mini-dental implants had provided immediate support for prostheses during the integration of traditional root-form endosteal implants. Upon explantation, the mini-dental implants were in a state of health and functioning in their intended purpose. Histologically, the bone appeared to be integrated to the surface of the implant at the light microscope level, and the bone appeared to be relatively mature and healthy in the areas observed, more so than one would expect in this amount of time from insertion of mini-dental implants with immediate loading. A discussion of the purposes and technique used for insertion and removal of these mini-dental implants is discussed. This is the first human histological report on the auto-advance technique with immediate loading of mini-dental implants, demonstrating feasibility in ongoing applications.

[The Bambuí Project: a population-based study of factors associated with regular utilization of dental services in adults].

A cross-sectional study was conducted in Bambuí, Minas Gerais, to identify factors associated with regular use of dental services. Participants were interviewed with a structured questionnaire and previously validated questions. 999/1,221 (81.8%) randomly selected individuals aged > 18 years participated in the Bambuí dental survey. Of these, 654 out of 656 individuals who had at least one natural tooth and had visited a dentist during their lifetime participated in the study. Results adjusted by multiple logistic regression showed that regular use of dental services was significantly related to having > 8 and 4-7 years of schooling (OR = 9.90; 95% CI = 2.90-33.77 and OR = 3.87; 95% CI = 1.11-13.51, respectively), having a preference for restorative treatment rather than extraction (OR = 4.91; 95% CI = 2.23-10.79), having no present need of dental treatment (OR = 4.87; 95% CI = 3.17-7.49), and belief that visiting the dentist prevents tooth decay and gum disease (OR = 1.73; 95% CI = 1.13-2.65). The results show that regular use of dental services was related to factors distributed in the Andersen and Newman model (1973) explaining use of dentistry services.

[Atraumatic restorative treatment to control dental caries: history, characteristics, and contributions of the technique].

This paper presents relevant scientific information on the history, characteristics, and contributions of atraumatic restorative treatment (ART) for use in preventing and controlling dental caries. Within the area of oral public health, ART has been for years an economical, effective method for preventing and controlling caries in vulnerable populations. Among other things, ART reduces the stress and anxiety in patients that conventional restoration methods produce. This technique promises major benefits for Latin America. However, given its limitations with dental cavities on two or more surfaces, it is recommended that more research on this approach be encouraged, with the aim of improving the technique's effectiveness based on its characteristics, indications, and technical merits.

Implant-supported anterior tooth restoration.

Various options are available for restoring anterior teeth. Their choice is dictated by the severity of infection of the teeth to be extracted and the pocket depth. Immediate single-stage implant placement proved to be the least traumatic option, which best preserved the soft tissue. A differential use of surgical and prosthodontic techniques is indispensable to account for conditions in the individual case. Given an adequate amount of hard tissue, soft tissue contours can be expected to return to normal. Immediate implants combined with a soft tissue support have been found to ensure that the depth of even larger pockets is stable for years.

The use of dental services in a population in Northern Norway.

The utilization of dental services was studied by means of records from dentist's files, a method which permits gathering of detailed information with high reliability and validity. 53% of the adult population of 358 persons living in a coastal community in Northern Norway had visited a dentist during a period of two years. In the group of 13% who were considered to be regular treatment attenders, number of teeth, sex and socio-economical status were the most influential predictors of utilization. Among the 182 persons with 10 or more remaining teeth, 59% had made preventive and restorative dental visits, and in this group there was a dominating proportion of women, young people and people with high income and/or social class. In contrast, only six persons out of 61 with one to nine remaining teeth had made such visits. People in social class 3 were overrepresented among the 26% of the population who visited a dentist because of extractions or complete denture services. The treatment profile according to age showed that younger people used most of their treatment time on consultations, preventive measures and conservative treatments, while fixed and removable prosthetics constituted a major part of the treatment time among elderly people.

In vivo wear pattern of experimental composite resins based on different resin monomers.

This study investigated the effects of various monomer systems on composite resin wear in vivo. Experimental light-cured composite resins were prepared employing four different monomer systems: (1) Bis-GMA type, (2) D-2. 6E type, (3) UDMA type, (4) UTMA type. The resin monomers consisted of 70wt% main monomer and 30wt% TEGDMA. These composites contained 80wt% fine quartz. The resins were placed in 2 mm diameter cylindrical cavities located in the occlusal contact area or the contact free area in cast crowns, temporarily set in a mouth. The crowns were removed at monthly intervals, for longitudinal SEM observation. Two months after setting, wear was analyzed, using an electron probe surface roughness analyzer. Microabrasion of the resin matrix and loss of filler particles were observed for all types of monomer systems. The effect of matrix resin systems on occlusal wear was smaller than that of filler systems.

[In vitro comparison of marginal adaptation of different filling materials. II. Effect of the site and method of preparation on the marginal adaptation].

In a two-month in vitro experiment we examined the marginal adaptation of ten dental materials. Fifty Class II restorations were prepared extending to the cemento-enamel junction. The cavities of the composite restorations were bevelled at the vestibulo-occlusal and -approximal enamel margins, on the other side enamel and gingival margins were prepared conventionally. The specimens were thermocycled and examined with SEM. The microleakage was measured at the vestibulo-occlusal and -approximal tooth-filling junction, where adhesive technique was used, and at the gingival, oroocclusal and -approximal margins, which were not bevelled before. The obviously most important conclusion of the study is, that in the case of deep Class II cavities the amalgam has a better adaptation at the gingival margin than the examined composite resins.
