Long-term implant survival and success: a 10-16-year follow-up of non-submerged dental implants

This prospective 3-year follow-up clinical study evaluated the survival and success rates of 3DP/AM titanium dental implants to support single implant-supported restorations. After 3 years of loading, clinical, radiographic, and prosthetic parameters were assessed; the implant survival and the implant-crown success were evaluated. Eighty-two patients (44 males, 38 females; age range 26–67 years) were enrolled in the present study. A total of 110 3DP/AM titanium dental implants (65 maxilla, 45 mandible) were installed: 75 in healed alveolar ridges and 35 in postextraction sockets. The prosthetic restorations included 110 single crowns (SCs). After 3 years of loading, six implants failed, for an overall implant survival rate of 94.5%; among the 104 surviving implant-supported restorations, 6 showed complications and were therefore considered unsuccessful, for an implant-crown success of 94.3%. The mean distance between the implant shoulder and the first visible bone-implant contact was 0.75 mm (±0.32) and 0.89 (±0.45) after 1 and 3 years of loading, respectively. 3DP/AM titanium dental implants seem to represent a successful clinical option for the rehabilitation of single-tooth gaps in both jaws, at least until 3-year period. Further, long-term clinical studies are needed to confirm the present results.

Abstract Background and purpose The aim of this clinical study was to investigate the clinical long-term and patient-reported outcome of dental implants in patients with oral cancer. In addition, analysis of the influence of radiation therapy, timing of implant insertion, and augmentation procedures on implant survival was performed. Material and methods This retrospective study investigated the clinical outcome of 711 dental implants in 164 oral cancer patients, inserted by experienced surgeons of the Department of Oral and Maxillofacial Surgery, University Medical Center Mainz, Germany. Oral health-related quality of life (OHRQoL) was evaluated. Results Cumulative 5-year and 10-year implant survival rates for all included implants were 87.3% and 80.0%. Implants placed straight after ablative surgery (primary implant placement) and implants placed after completing the oncologic treatment (secondary implant placement) showed a comparable implant survival (92.5% vs. 89.5%; p = 0.635). Irradiation therapy had no significant influence on implant survival of secondary placed implants (p = 0.929). However, regarding implant site (native bone vs. augmented bone) and radiation therapy (non-irradiated bone vs. irradiated bone), implants inserted in irradiated bone that received augmentation procedures showed a statistically significant lower implant survival (p < 0.001). Patients reported a distinct improvement in OHRQoL. Conclusions Promising long-term survival rates of dental implants in patients after treatment of oral cancer were seen. In addition, patients benefit in form of an improved OHRQoL. However, bone augmentation procedures in irradiated bone may result in an impaired implants’ prognosis.

Bone Level

Short 6 mm dental implants are considered as an alternative to the maxillary sinus elevation and bone augmentation procedure where there is a reduced alveolar ridge height. The aim of this study was to compare the implant survival rate between short dental implants (6 mm) and regular length implants (11–13 mm) when placed in combination with bone grafting and loaded with a single non splinted crown, seven years after placing the implant. It was conducted as a controlled clinical study of 30 patients with partial edentulism in the posterior maxilla. The protocol included radiological and clinical evaluation of the C/I ratio (length of the superstructure divided by the length of the implant crestal part), marginal bone level (MBL), ultrasonography measurement of soft tissue surrounding implant (STT), patient-reported outcomes, and biological and technical complications. A total number of 28 implants (93%) remained integrated during follow-up period. MBL of 0.50 and 0.52 mm was observed for short implants and regular implants, respectively. MBL was checked for correlation with STT, and a negative correlation was found between MBL: STT. Our study has demonstrated a significantly lower implant survival rate for short implants compared to regular implants (87% compared to 100%). Despite the loss of several implants, good clinical results were achieved in the remaining implants in both groups. It is, therefore, worth considering short implants as an alternative to regular implants with a sinus lift surgery.

Clinical Records

This retrospective study evaluated the survival rate of short, sandblasted acid-etched surfaced implants with 6 and 8 mm lengths with at least 120 days of follow-up. Data concerning patient, implant and surgery characteristics were retrieved from clinical records. Sandblasted and acid-etched (SLA)-surfaced tissue-level 6 mm (TL6) or 8 mm (TL8) implants or bone-level tapered 8 mm (BLT8) implants were used. Absolute and relative frequency distributions were calculated for qualitative variables and mean values and standard deviations for quantitative variables. A Cox regression model was performed to verify whether type, length and/or width influence the implant survival. The cumulative implant survival rate was assessed by time-to-event analyses (Kaplan–Meier estimator). In all, 513 patients with a mean age of 58.00 ± 12.44 years received 1008 dental implants with a mean follow-up of 21.57 ± 10.77 months. Most implants (78.17%) presented a 4.1 mm diameter, and the most frequent indication was a partially edentulous arch (44.15%). The most frequent locations were the posterior mandible (53.97%) and the posterior maxilla (31.55%). No significant differences were found in survival rates between groups of type, length and width of implant with the cumulative rate being 97.7% ± 0.5%. Within the limitations of this study, the evaluated short implants are a predictable option with high survival rates during the follow-up without statistical differences between the appraised types, lengths and widths.

We report outcomes of 228 consecutive patients with total joint arthroplasty using the Arpe® prosthesis, among which 216 trapeziometacarpal joints in 199 patients had a minimum of 10 years follow-up. The cumulative survival rate of the 216 implants at 10 years using the Kaplan–Meyer method was 93%. Two hundred joints were functional and painless. We found good integration and positioning of the components in 184 (93%) of the joints. Sixteen prostheses failed. We conclude that this implant has acceptable long-term survival rate and restores good hand function. We also report our methods to improve implant survival and to decrease the risk of component malpositioning, and failure rate. Level of evidence: II

Background The Universal 2 is a widely used total wrist implant that aims to maintain function of the wrist. Purpose Promising mid-term results of the Universal 2 total wrist implant are described in the literature. This study evaluates the long-term results in terms of implant survival and patient satisfaction. Patients and Methods Patients who received a Universal 2 implant between 2004 and 2009 were retrospectively identified through a database search. Clinical outcome and complications of the implant were assessed by examination of the patient's medical records, X-rays, and a questionnaire, consisting of the Patient-Rated Wrist and Hand Evaluation questionnaire (PRWHE) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaires and additional questions. Results Twenty-five patients (26 wrists) were included in this study. Twenty-one (81%) Universal 2 implants remained in situ after a mean follow-up of 11 years. Moderate PRWHE (44) and QuickDASH (41) scores were found in these cases. Five Universal 2 implants failed and were converted to a total wrist arthrodesis after a mean period of 9.2 years due to distal component loosening (n = 3), recurrent luxation (n = 1), or recurrent synovitis (n = 1). Twenty-three (92%) patients were (very) satisfied with the Universal 2 implant. Conclusion The Universal 2 demonstrates a high (81%) implant survival with a high patient satisfaction after a mean follow-up of 11 years. Prospective studies of the Universal 2 implant are necessary to objectify improvement in wrist function and to provide a better comparison to other fourth generation wrist implants.

Traumatic Arthritis

Background Post-traumatic arthritis of the hip is a degenerative condition that commonly affects young patients. In this study, we evaluate long-term implant survival and patient-reported outcomes after primary total hip arthroplasty (THA) in patients aged 35 or younger with post-traumatic arthritis of the hip. Methods We conducted a retrospective study with follow-up. A chart review was performed to identify young patients with post-traumatic arthritis of the hip treated with primary THA. Follow-up surveys were conducted to determine implant survival and patient-reported outcomes. Implant survival was assessed using Kaplan-Meier survival analysis, and patient outcomes were determined using the hip disability and osteoarthritis outcome score (HOOS). Results We studied 42 patient s (44 THAs) with a mean time to follow-up of 14 years. The 10-year implant survival rate was 87% and 20-year implant survival rate was 41%. Implant survival did not differ based on patient age, gender, implant type, bearing surface, or use of cement for implant fixation (p>0.05). The mean HOOS scores at follow-up were 87 for pain, 85 for symptoms, 89 for ADLs, and 76 for sports. HOOS scores were significantly worse in patients that had undergone revision THA (p<0.05). Conclusions Young patients with post-traumatic arthritis of the hip have good long-term outcomes after THA. However, revision THA is predictive of worse long-term outcomes.

Category: Ankle Arthritis Introduction/Purpose: Hemophilia is a rare hematological disease associated with spontaneous joint hemorrhaging causing hemophilic arthropathy. Symptoms comprise joint pain and deformity, paired with loss of function. In the presence of advanced joint deterioration, therapeutic options are confined to either arthroplasty or arthrodesis. For the ankle, the latter is still referred to as the procedure of choice. However - in light of its capacity to reduce pain while preserving ankle motion - total ankle replacement (TAR) has recently gained acceptance as an alternative. The aim of this study was to investigate the mid- to long-term results of TAR in hemophilic ankle arthropathy. Methods: Seventeen TARs were implanted between 1998 and 2012 (mean age: 43 years). Preoperative demographic and disease specific data, complications and revision surgeries were recorded. With a mean follow-up of 9.3 years (range, 2.2-17.8) implant survival was estimated using Kaplan-Meier analysis. Follow-up assessment of 12 TARs was performed after 9.6 years (5 lost to follow-up). Satisfaction and pain scales, the AOFAS hindfoot-score, and the SF-36 were obtained to assess clinical outcome. Radiographic evaluation of pre- and follow-up radiographs was conducted. Results: Three cases (17.6%) had undergone TAR removal secondary to loosening at an average interval of 7.5 years. The estimated implant survival was 94% at 5, 85% at 10, and 70% at 15 years (95% CI, 11.9-17.7). The mean estimated implant survival was 14.77 years (95% CI, 11.9-17.7). The mean level of satisfaction was 76%, and of pain 2/10 (VAS). ROM had increased significantly (p=0.037). The SF-36 summary scores were comparable to those of a matched standard population. The AOFAS hindfoot-score averaged 81/100 points. Conclusion: TAR is a viable treatment option for advanced hemophilic ankle arthropathy. Based on the herein presented follow- up, implant survival compares to that of non-hemophilic populations. Clinical mid- to long-term results are favorable. However, the majority of follow-up radiographs revealed component loosening and/or periprosthetic lucency. Considering the study population’s young age and specific risk factors, need for revision surgery secondary to symptomatic component loosening may arise.
