Mini dental implants: an adjunct for retention, stability, and comfort for the edentulous patient.

OBJECTIVE: This article examines the success of mini-dental implants (MDI'S) by assessing four subjective measures of patient satisfaction for MDI's in the edentulous maxilla and mandible: comfort, retention, chewing ability and speaking ability. Success rates, surgical techniques, and financial advantages of the MDI's are reviewed. STUDY DESIGN: Thirty consecutive patients received four MDI's between the mental foramen of the mandible from 9/18/2003 to 10/22/2004. Questionnaires were sent to all thirty patients an average of 5 months postoperatively. The patients ranked comfort, retention, chewing ability, and speaking ability from 1 to 10 (1=poor and 10=excellent). RESULTS: A total of 116 MDI's were placed in 13 months and 113 remain stable for a 97.4% implant success rate. Pre-operatively patients rated their retention at 1.7+/-0.42 and post-operatively at 9.6+/-0.37, for a difference of 7.9 (p=3.6-19). Comfort was the next greatest improvement, with a pre-operative rating of 2.2+/-0.63 and a post-operative rating of 9.4+/-0.45, for a difference of 7.2 (p=3.5-15). Chewing ability also improved, with a difference of 7.0 (p=2.9e-16). In the final category of speaking ability, the pre-operative to post-operative difference was 3.2 (p=1.1e-5). CONCLUSION: MDI's are a highly successful implant option for patients with poor tolerance to maxillary and mandibular prosthesis. The implants are relatively affordable and overall patient satisfaction is excellent.

Critical evaluation of patient responses to dental implant therapy.

STATEMENT OF PROBLEM: Successful rehabilitation of the edentulous condition requires functional and psychosocial adaptation by the patient. Quality of life is markedly affected by the amount of satisfaction or dissatisfaction with their dental therapy. Patient concerns are primarily related to comfort, function, and esthetics. When these do not meet the patients expectations, anxiety, insecurity, diminished self-esteem, and introversion are typical psychosocial responses. PURPOSE: The objectives of the study were to assess the patient's subjective feelings about: (a) comfort, (b) function, (c) esthetics, (d) speech, (e) self-image, and (f) overall dental health with their existing complete dentures, and after implant therapy and prosthodontic rehabilitation. MATERIAL AND METHODS: Two health-related quality of life (HRQL) questionnaires were developed to evaluate the effectiveness of dental implant therapy; one dealing with their feelings about their conventional complete dentures, and the second dealing with implant therapy. The first questionnaire was administered with supervision before receiving implant treatment. The second questionnaire was administered within 1 year after completion of prosthetic rehabilitation. Twenty-six patients who received implants to support a mandibular prosthesis and a new maxillary denture formed the experimental population. RESULTS: Discriminative and evaluative analysis of subjective patient responses provided reliable, accurate, and reproducible results. Assessment of subject feelings before and after implant therapy and prosthodontic rehabilitation demonstrated significant differences when before treatment responses were compared with the responses after therapy. CONCLUSIONS: Significant differences for comfort, function, speech, esthetics, self-image, and dental health were demonstrated when conventional complete dentures and dental implant therapy were compared. HRQL data provided scientific evidence of an improved quality of life after dental implant therapy (p < 0.000).

Report of four familial cases with congenitally missing mandibular incisors.

Heredity is one of the possible factors associated with congenitally missing mandibular incisors. We report four cases--a mother and three daughters--in an attempt to examine this hypothesis. Different treatment modalities have been used to treat malocclusions stemming from this problem. The treatment philosophy of consolidating mandibular spaces and obtaining a stable occlusion, thereby preventing the removal of maxillary teeth or the use of a mandibular prosthesis, is presented.

Medical devices; classification of temporomandibular joint implants--FDA. Final rule.

The Food and Drug Administration (FDA) is classifying four temporomandibular joint (TMJ) implants, the total temporomandibular joint prosthesis, the glenoid fossa prosthesis, the mandibular condyle prosthesis, and the interarticular disc prosthesis (interpositional implant), into class III (premarket approval). These actions are being taken under the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Medical Device Amendments of 1976 (the 1976 amendments) and the Safe Medical Devices Act of 1990 (the SMDA).

[Titanium-coated hollow screw and reconstruction plate system for the bridging of jaw defects. II. Possible reconstruction variants with the THRP system].

The advantages and special features of the THRP-system enabled us to develop new operative techniques. The combination of the advantages of external fixation devices and those of the internal osteosynthesis has proved to be decisive in order to obtain good results. The clinical results in 30 patients confirm the recently published findings from animal studies. Histological examination of human specimens comparing 2 types of screws developed by us are discussed.

Preventive goals in oral implantology.

Preventive dentistry is mainly concerned with caries and periodontal disease and little or no attention is paid to the prevention of alveolar bone loss. An overdenture contributes to the preservation of alveolar bone and offers a number of advantages in comparison to a conventional complete denture. After tooth extraction the atrophy of edentulous lower jaws can be prevented or delayed by using implants supporting an overdenture or a fixed mandibular prosthesis. Hydroxyapatite implants have been studied as submerged tooth root substitutes and have proven to be able to preserve the bulk of the alveolar ridge. A drawback of this submucosal implant is that the ridge maintenance depends solely on the physical presence of the hydroxyapatite implants. If implants support an overdenture or a fixed prosthesis they also play a role in maintaining the function of the bone in the different stages of reduction of the mandible. In this paper a classification for the different resorption stages of the mandible is presented and is used to determine the correct moment for preventive implantology. In addition the use of a lingualised occlusion is discussed as a contribution to the preventive goals in oral implantology.

Restoring lost vertical dimension of occlusion using dental implants: a clinical report.

The successful rehabilitation of a patient with severe vertical overlap resulting from the loss of posterior occlusal support and excessive wear of the mandibular incisors is described. The treatment plan necessitated extraction of the remaining periodontally compromised mandibular teeth and placement of eight implants. Lost occlusal vertical dimension and morphologic facial height were restored using a fixed detachable implant-supported mandibular prosthesis, and the maxillomandibular relationship was transformed from Class II to Class I.

[Ceramic implants to benefit complete lower dentures].

In our Department of implantology, 141 ceramic implants were put in place with the objective of stabilizing a complete mandibular prosthesis in 39 patients. Despite the small number of cases reported, statistical analysis was informative because of the homogeneity of the conditions: the same indication for a prosthesis; the same operator for the surgery as well as the prosthesis; The very good follow-up with all but 2 patients having been monitored regularly. In addition to the finding that our results are practically superposable on those obtained with titanium implants over the same period of time. We share our experience with ceramic materials; dispel their reputation of fragility, especially since the advent of zirconium; and emphasize the simplicity of these "artificial roots" that can be use without prefabricated and costly intermediate parts.

Practical implant dentistry--the mandibular removable overdenture prosthesis.

The fully edentulous mandible presents functional, esthetic, and psychological challenges for the patient and the dentist. The mandibular overdenture supported by endosseous implants can provide a superior treatment modality, overcoming many of the difficulties inherent in the conventional denture. Advantages cited are increased denture retention, improved chewing efficiency, maintenance of bone height, replacement of lost anatomy, increased denture stability, reduction of soft tissue coverage and extension of the prosthesis, and easy access for hygiene maintenance. The major disadvantage rests with the patient's intolerance of a removable prosthetic design.

Use of personal computers for Gothic arch tracing: analysis and evaluation of horizontal mandibular positions with edentulous prosthesis.

STATEMENT OF PROBLEM: Determining mandibular position for an edentulous patient raises the question of whether to emphasize centric relation or muscular position. This challenge results from the lack of a convenient procedure for quantifying the horizontal mandibular position, which can be determined by a variety of methods. PURPOSE: This study analyzed and evaluated the horizontal mandibular positions produced by different guidance systems. MATERIAL AND METHODS: Twenty-six edentulous subjects with no clinical evidence of abnormality of temporomandibular disorder were selected. Horizontal position data for the mandible obtained by gothic arch tracing was loaded into a personal computer by setting the sensor portion of a digitizer into the oral cavity to serve as a miniature lightweight tracing board. By connecting this with a digitizer control circuit set in an extraoral location, each mandibular position was displayed in a distinguishable manner on a computer display in real time, then recorded and analyzed. RESULTS: The gothic arch apex and tapping point varied, depending on body position. In the supine position, the gothic arch apex and the tapping point were close to the mandibular position determined by bilateral manipulation. CONCLUSION: This system provides effective data concerning mandibular positions for fabrication of dentures.
