Dental implants in geriatric patients: a retrospective study of 47 cases

PURPOSE: To determine the overall success of dental implants placed in geriatric patients. PATIENTS: Dental implants were placed in 47 geriatric patients who were 79 or more years of age at the time of the procedure. The study group was composed of 27 men and 20 women, with a median age of 89 years and a range of 79 to 99 years of age at the time of implant surgery. A total of 73 dental implants were placed in the maxilla and 87 dental implants placed in the mandible. All implants were restored with fixed implant-supported prostheses or removable implant-supported prostheses. Eleven of the patients underwent maxillary sinus augmentation with porous hydroxyapatite and platelet-rich plasma. Seven patients had their implants immediately loaded. RESULTS: A total of 160 dental implants were placed in the 47 geriatric patients. One hundred fifty-nine integrated successfully. In the case of the failed implant, the site was grafted and another implant was placed 5 months subsequent to the initial failure. This replacement implant integrated and has been in function for 6 months. The survival rate for dental implants placed in the maxilla was 99% and in the mandible was 100% in our geriatric population. CONCLUSION: Treatment with dental implants can be predictable and safe for the rapidly growing geriatric population. Geriatric patients who are medically stable are suitable candidates for osseointegrated implant surgery, which facilitates oral function, comfort, and quality of life. A review of the 47 geriatric patients treated supports the conclusion that dental implants can be successfully placed and restored with fixed implant-supported or removable implant-supported prostheses.

Identification of dental implants through the use of Implant Recognition Software (IRS)

AIM: To develop computer software to allow general dental practitioners and others to identify unidentified implants in patients' mouths using a range of criteria. METHODS: Internet searches for implant manufacturing companies worldwide in all languages using terms: dental implants, dental implant manufacturers and dental implant companies. Once identified, all relevant information including images regarding dental implant products was collected even that for discontinued products. A program was then devised using key design factors to enable identification of individual implants. RESULTS: The searches produced details for 87 implant manufacturers based in 21 countries with 231 different implant designs. The resultant program has been successfully trialled and used in both general dental practice and for forensic identification. CONCLUSION: The program developed provides a valuable adjunct to the identification of implant systems present in patients' mouths.     

Progress and trends in patients' mindset on dental implants. II: implant acceptance, patient-perceived costs and patient satisfaction

Objectives: Compared with widespread investigations on dental implant survival and biologic parameters, patient‐based outcomes of implant dentistry have been neglected for years and are now becoming more popular. The aim of this representative opinion poll was to assess the up‐to‐date patients' mindset on dental implants and draw comparisons with the results published in 2003. Material and methods: One thousand adults – representative for the Austrian population – were presented with a total of 16 questionnaire items regarding acceptance and subjectively perceived costs of dental implant treatment as well as patient satisfaction with implant‐supported rehabilitation. Results: The implant acceptance rate was 56%, while 23% of the interviewees decidedly rejected implant treatment (same rate as in 2003), especially those over 50 years of age. Only 5% had themselves undergone implant treatment and 22% reported to know someone fitted with implants. The estimated costs of implant treatment were significantly higher than those in 2003, and three‐quarters felt that the prize was too high and that the sick fund or social security agencies should bear them. Satisfaction scores were significantly higher among interviewees wearing implant‐supported rehabilitations compared with those with conventional fixed or removable dentures. Conclusions: Little has changed in patients' attitude toward dental implants compared with the representative opinion poll in 2003. Neither implant acceptance nor implant prevalence in the Austrian population demonstrated upward trends. Professional public relations efforts are indicated to drop resentments and increase patient acceptance of dental implants as a treatment modality. To cite this article :

Retrospective multicenter cohort study of the clinical performance of 2-stage implants in South Korean populations

PURPOSE: To evaluate long-term follow-up clinical performance of dental implants in use in South Korean populations. MATERIALS AND METHODS: A retrospective multicenter cohort study design was used to collect long-term follow-up clinical data from dental records of 224 patients treated with 767 2-stage endosseous implants at Ajou University Medical Center and Bundang Jesaeng Hospital in South Korea from June 1996 through December 2003. Exposure variables such as gender, systemic disease, location, implant length, implant diameter, prosthesis type, opposing occlusion type, and date of implant placement were collected. Outcome variables such as date of implant failure were measured. RESULTS: Patient ages ranged from 17 to 71.7 years old (mean age, 45.6 years old). Implants were more frequently placed in men than in women (61% versus 39%, or 471 men versus 296 women). Systemic disease was described by 9% of the patients. All implants had hydroxyapatite-blasted surfaces. Most of the implants were 3.75 mm in diameter. Implant lengths 10 mm, 11.5 mm, 13 mm, and 15 mm were used most often. Differences of implant survival among different implant locations were observed. Implants were used to support fixed partial dentures for the majority of the restorations. The opposing dentition was natural teeth for about 50% of the implants. A survival rate of 97.9% (751 of 767) was observed after 4.5 years (mean, 1.95 +/- 1.2 years). CONCLUSION: Clinical performance of 2-stage dental implants demonstrated a high level of predictability. The results achieved with a South Korean population did not differ from results achieved with diverse ethnic groups.     

Three Tumor Patients with Total Maxillectomy Rehabilitated with Implant‐Supported Frameworks and Maxillary Obturators: A Follow‐Up Report

Background: Few reports are available on treatment using implant‐supported frameworks with maxillary obturators after total maxillectomy on tumor patients. Purpose: To describe, evaluate, and report the clinical and radiographic performance of implant‐supported frameworks and maxillary obturators after maxillectomy during the first years of function. Materials and Methods: Three patients with cancer in the maxillary region treated by total maxillectomy were rehabilitated. Seventeen dental and two craniofacial implants were installed, and the patients each received implant‐supported, screw‐retained, three‐unit frameworks with a U‐shaped bar and obturators retained by four magnetic attachments. Clinical and radiographic data were collected up to 7 years of follow‐up. Results: The frequency of complications was low. Two craniofacial implants and one dental implant were loose and removed at abutment connection. No implants were lost after framework connection, and the mean marginal bone loss was small. Conclusion: Within the limitations of this report, dental implants are useful for rehabilitation of total maxillectomy patients, and a three‐unit, screw‐retained, implant‐supported framework with maxillary obturator retained by magnetic attachment is a successful treatment concept for this patient group.     

Analysis of failed commercially pure titanium dental implants: a scanning electron microscopy and energy-dispersive spectrometer x-ray study

BACKGROUND: The failure of osseointegration in oral rehabilitation has gained importance in current literature and in clinical practice. The integration of titanium dental implants in alveolar bone has been partly ascribed to the biocompatibility of the implant surface oxide layer. The aim of this investigation was to analyze the surface topography and composition of failed titanium dental implants in order to determine possible causes of failure. METHODS: Twenty-one commercially pure titanium (cpTi) implants were retrieved from 16 patients (mean age of 50.33 +/- 11.81 years). Fourteen implants were retrieved before loading (early failures), six after loading (late failures), and one because of mandibular canal damage. The failure criterion was lack of osseointegration characterized as dental implant mobility. Two unused implants were used as a control group. All implant surfaces were examined by scanning electron microscopy (SEM) and energy-dispersive spectrometer x-ray (EDS) to element analysis. Evaluations were performed on several locations of the same implant. RESULTS: SEM showed that the surface of all retrieved implants consisted of different degrees of organic residues, appearing mainly as dark stains. The surface topography presented as grooves and ridges along the machined surface similar to control group. Overall, foreign elements such as carbon, oxygen, sodium, calcium, silicon, and aluminum were detected in failed implants. The implants from control group presented no macroscopic contamination and clear signs of titanium. CONCLUSION: These preliminary results do not suggest any material-related cause for implant failures, although different element composition was assessed between failed implants and control implants.
