The aim of this technique is to provide adequate interocclusal distance (3 mm) allowing preprosthetic management. A bone block was cut with piezosurgery and extracted, leaving the crestal cortical bone intact. The free crestal alveolar bone was fixed to the maxilla with 2 dental implants. After 3 months of follow-up, abutment surgery was performed and osseointegration was evident with adequate interocclusal height (7 mm) allowing prosthetic management.

Abstract Little data have been published on the survival rates of implants placed in dental residency programs. This study reports on the outcome of dental implants placed by first-year general dentistry residents in the University of Florida College of Dentistry–Jacksonville Clinic. The patients for this study received both surgical and restorative implant therapy from 1998 to 2002. A total of 108 patients (62 women, 46 men) were treated with dental implants. On average, a patient was 52.9 years old and received 2.6 implants. A variety of simple and complex restorative procedures were performed. Advanced general dentistry residents in conjunction with supervisory faculty treated all cases. The cumulative implant survival was 98.2%. Follow-up varied from 6 months to 4 years after placement. Cases included implants not yet loaded as well as implants loaded for 3 years or more. The findings of this study compare favorably with published studies and were unexpected in light of the residents' limited clinical experience.

The Relationship

Abstract The relationship between bisphosphonates (BP) and dental implant failure has not been fully elucidated. The purpose of this retrospective radiographic study was to examine whether patients who take BP are at greater risk of implant failure than patients not using those agents. Treatment records of 362 consecutively treated patients receiving endosseous dental implants were reviewed. The patient population consisted of 227 women and 135 men with a mean age of 56 years (range: 17–87 years), treated in the University at Buffalo Postgraduate Clinic from 1997–2008. Demographic information collected included age, gender, smoking status, as well as systemic conditions and medication use. Implant characteristics reviewed included system, date of placement, date of follow-up radiographs, surgical complications, number of exposed threads, and implant failure. The relationship between BP and implant failure was analyzed using generalized estimating equation (GEE) analysis. Twenty-six patients using BP received a total of 51 dental implants. Three implants failed, yielding success rates of 94.11% and 88.46% for the implant-based and subject-based analyses, respectively. Using the GEE statistical method we found a statistically significant (P  =  .001; OR  =  3.25) association between the use of BP and implant thread exposure. None of the other variables studied were statistically associated with implant failure or thread exposure. In conclusion, patients taking BP may be at higher risk for implant thread exposure.

Abstract Survival rates of multiple implant designs placed in various clinical situations average more than 90%. However, little data have been published on the survival rates of implants placed in dental residency programs. This study reports on the outcome of dental implants placed by first-year general dentistry residents in the University of Florida College of Dentistry–Jacksonville Clinic. The patients for this study received both surgical and restorative implant therapy from 1998 to 2005. A total of 263 patients (147 women, 116 men) were treated with dental implants. On average, a patient was 55.5 years old and received 3 implants. A variety of simple and complex restorative procedures were performed. Advanced general dentistry residents in conjunction with supervisory faculty treated all cases. The cumulative implant survival was 96.6%. Follow-up varied from 6 months to 7 years after placement. Cases included implants not yet loaded as well as implants loaded for 6 years or more. The findings of this study compare favorably with published studies and were unexpected in light of the residents' limited clinical experience.

Damping Model

Multiple variables have been shown to influence early marginal bone loss around dental implants. Among these factors, the location of the microgap related to the alveolar crest, occlusion, crest module and soft tissue thickness were reported to be important factors for deciding the final outcome of the implant treatment. The purpose of this study was to establish a damping model to simulate the mechanical function of dental implants in the oral cavity. The experimental implant model consisted of a screw-type implant (10[Formula: see text]mm). The implant was placed into epoxy resin which was used to simulate bone tissue. In this study, two kinds of epoxy resin were used: PL-1 (with elastic moduli of 2900[Formula: see text]MPa) and PL-2 (210[Formula: see text]MPa) were used to simulate cortical bone and cancellous bone, respectively. Above bone block, a soft lining material was used to simulate the soft tissue around implant. In addition, two-implant model with various distance between implants were established to discuss the effect of soft tissue effect on the damping factors (DF) of the implant system. A noninvasive impulse-forced vibration technique was used to detect the damping factors of the implant models as previous reported. Briefly, the signal excitation was detected through the micro-phone and sent to the spectrum analyzer. The frequency response was obtained from a vibration-time histogram using Fast Fourier Transform software. The DF value of the signal dental implant model was detected to be [Formula: see text]. This value is closed to the in vivo data that was reported previously. This result showed that the model established in this study is a validated model for damping analysis. Furthermore, the DF value of a dental implant surrounded with 3[Formula: see text]mm soft tissue ([Formula: see text]) is significantly higher than the implant with 2[Formula: see text]mm-surround soft tissue ([Formula: see text]). In addition, implant models with larger interval distance between implants showed higher DF values. According to the results of this study, it is reasonable to suggest that dental implant surrounded with higher amount soft tissue may reduce more vibration amplitude while an occlusal force was applied to a dental implant. This vibration reducing effect may be helpful to reduce alveolar bone resorption around implants.

Abstract Purpose To integrate the available data published on patients with epidermolysis bullosa (EB) rehabilitated with dental implants, as well as to review the recommendations for EB patients receiving implants. Methods An electronic search was undertaken in February 2019 in five databases. Results Sixteen publications were included, reporting 28 patients with EB, rehabilitated with 161 dental implants. The mean ± SD patients’ age at implant surgery was 34.7 ± 12.1 years (range, 13–56). Only one implant was placed in the molar region, all other implants were placed in the incisor, canine, and premolar regions. Patients received a mean ± SD of 5.8 ± 2.8 implants (range, 2–11). Most of the patients received implant-supported fixed prostheses (fixed partial 14.3%, fixed full-arch 60.7%, overdenture 25%). Implant and prosthesis failure rates were 1.3% and 0%, respectively. The two implant failures were detected before or at the abutment connection. The mean ± SD follow-up time was of 39.2 ± 24.5 months (range, 6–111). The EB patient quality-of-life improved considerably as a result of treatment with dental implants. There is a series of dental care considerations that should be followed to smooth the implant treatment in EB patients. Conclusions The dental implant failure rate in EB patients seems to be very low, although the few cases reported in the literature were followed up for a short mean period, i.e., just a little bit longer than 3 years. More cases followed up for a long period are needed in order to be able to make a more reliable prognosis for the long-term oral rehabilitation of EB patients with dental implants.

The relationship between bone mineral density and tooth loss in men is unclear. The aim of this retrospective cohort study was to determine if relative metacarpal bone area (MCA) predicts tooth loss in a cohort of 273 male participants in the Dental Longitudinal Study and Normative Aging Study of the Department of Veterans Affairs. Outer and inner cortical bone widths of the middle metacarpal of the nondominant hand were measured on anteroposterior hand radiographs approximately 11 y apart. Baseline MCA was computed and categorized into quartiles. The men were followed from 1971 to 2015. Incident tooth loss during 2 intervals was examined: concurrent with the MCA measurements and long term over the total follow-up (17 ± 7 y). Radiographic alveolar bone loss (ABL) was measured on periapical radiographs as a percentage of the distance from the cementoenamel junction to root apex, and the number of teeth with ABL >40% was computed. Negative binomial generalized linear regression models estimated the mean number of teeth with ABL >40% and the number lost (concurrent and total), controlling for age, smoking, number of teeth at baseline, percentage teeth with ≥1 decayed/filled surface, and years of follow-up. At baseline, MCA was inversely related to number of teeth with >40% ABL. Men in the lowest MCA quartile (Q1) lost the most teeth, both concurrent with MCA measurements and long term, but the association differed by caries level (≤55% or >55% decayed/filled teeth). At the low caries level, the numbers lost in Q1 were 29% greater than in the highest MCA quartile (Q4). At the high caries level, the numbers lost in Q1 were more than twice those in Q4. Associations were attenuated when further controlled for number of teeth with ABL>40%. These findings suggest that systemic bone status plays a role in tooth loss and that the association may be mediated by alveolar bone loss. Knowledge Transfer Statement: Low relative metacarpal bone area was related to loss of alveolar bone and incident tooth loss in men. This information extends previous research, primarily studies of women, showing that osteoporosis adversely affects oral health. Knowledge of a patient’s systemic bone status may be important for managing his or her periodontal disease. Tooth loss in the absence of periodontal inflammation may signify systemic bone loss. Interprofessional communication is central to maintaining optimal oral and bone health.

Abstract The aim of the study was to evaluate the survival of implants with different implant-abutment connection systems, in patients who had two kinds of implants implanted. In total, 240 implants were implanted - 91 implants with conical abutment Morse connection, and 149 with an internal hexagonal connection. During the follow-up period of 3 years and 10 months, the percentage of lost implants with a conical implant-abutment connection was 1.1%. Regarding the implants with hexagonal implant-abutment connection, this figure was 0.7%. Our work shows that there is a need for further research on the survival of dental implants. In this, the influence of other factors should be explored that are related both to the specific implant treatment, as well as to socio-demographic factors
