Immediately provisionalized tapered conical connection implants for single-tooth restorations in the maxillary esthetic zone: a 5-year prospective single-cohort multicenter analysis.

OBJECTIVES: This open, single-cohort, multicenter, prospective study investigated the efficacy of immediately provisionalized tapered conical connection implant for single-tooth restorations in the anterior and premolar regions of the maxilla after 5 years of function. MATERIALS AND METHODS: All implants were placed in healed sites and immediately provisionalized. MBLs, soft-tissue parameters, and oral-health impact profile (OHIP) were evaluated at implant insertion, 6, 12, 24, 36, and 60 months. Paired Wilcoxon signed-rank tests and Kaplan-Meier survival analysis was used for statistical and implant survival/success analyses, respectively. RESULTS: Seventy-seven patients (81 implants) completed the 5-year follow-up. The 5-year cumulative survival and success rates were 97.8%, and the mean MBL change from implant insertion to 5 years was - 0.80 ± 1.13 mm. Optimal papilla index scores were observed at 90.1% of sites at 5 years compared with 32.8% of sites at insertion. Pink esthetic score, modified bleeding and plaque indices, and OHIP showed statistically significant improvement at the 5-year follow-up. CONCLUSIONS: Immediately provisionalized tapered conical connection implants promote marginal bone stability and excellent esthetic outcomes after 5 years of function. CLINICAL RELEVANCE: This treatment is a viable option for patients requiring immediately provisionalized single-tooth restorations in the esthetic zone and shows favorable long-term clinical outcomes, including marginal bone stability and excellent esthetics.

A prospective multicenter evaluation of immediately functionalized tapered conical connection implants for single restorations in maxillary anterior and premolar sites: 3-year results.

OBJECTIVES: This multicenter prospective clinical trial investigated immediately provisionalized, anodized, conical connection, tapered implants with platform shifting in maxillary anterior and premolar sites. MATERIALS AND METHODS: Patients requiring single-tooth implant-supported restorations in maxillary anterior and premolar sites were enrolled. Implants were immediately provisionalized and evaluated at insertion, 6 months, and annually thereafter. Outcome measures were marginal bone level change (ΔMBL), cumulative survival rate (CSR), and success rate, soft-tissue parameters, and oral health impact profile (OHIP). ΔMBL and Pink Esthetic Score were analyzed using Wilcoxon signed-rank tests. CSR was calculated using life table analysis. Other soft-tissue parameters were analyzed using sign tests. RESULTS: Of 94 enrolled patients (99 implants), 84 (88 implants) attended the 3-year follow-up. After an initial bone loss between implant insertion and 6 months (- 0.92 ± 1.23 mm), bone levels stabilized from 6 months to 3 years (0.13 ± 0.94 mm) with no significant change. The 3-year CSR was 98.9%, and the cumulative success rate was 96.9%. Papilla index scores of 2 or 3 were observed at 88.6% of sites at the 3-year visit compared with 32.8% at implant insertion. Improvements were observed for all other outcomes, including bleeding on probing, esthetics, plaque, and OHIP. CONCLUSIONS: This restorative protocol was associated with high primary stability, patient satisfaction, stable bone levels, and an overall improvement of the soft tissue outcomes over a 3-year period. CLINICAL RELEVANCE: The presented treatment is a viable option for single-tooth restorations of maxillary anterior teeth and premolars with successful short- to mid-long-term clinical outcomes.

An open prospective single cohort multicenter study evaluating the novel, tapered, conical connection implants supporting single crowns in the anterior and premolar maxilla: interim 1-year results.

OBJECTIVES: The aim of this multicenter prospective clinical study was to evaluate anodized tapered implants with a conical connection and integrated platform shifting placed in the anterior and premolar maxilla. MATERIALS AND METHODS: The study enrolled patients requiring single-tooth restorations in healed sites of maxillary anterior and premolar teeth. All implants were immediately temporized. Clinical and radiographic evaluations were conducted at implant insertion, 6 months, and 1 year. Outcome measures included bone remodeling, cumulative survival rate (CSR), success rate, soft-tissue health and esthetics, and patient satisfaction. Bone remodeling and pink esthetic score were analyzed using Wilcoxon signed-rank tests. CSR was calculated using life table analysis. Other soft-tissue outcomes were analyzed using sign tests. RESULTS: Out of 97 enrolled patients (102 implants), 87 patients (91 implants) completed the 1-year visit. Marginal bone remodeling was -0.85 ± 1.36 mm. After the expected initial bone loss, a mean bone gain of 0.11 ± 1.05 mm was observed between 6 months and 1 year. The CSR was 99.0%, and the cumulative success rate was 97.0%. Partial or full papilla was observed at 30.8% of sites at baseline, 87.2% at 6 months, and 90.5% at 1 year. Soft-tissue response, esthetics, and patient satisfaction all improved during the study period. CONCLUSIONS: Bone gain was observed following the expected initial bone loss, and soft-tissue outcomes improved suggesting favorable tissue response using anodized tapered conical connection implants. CLINICAL RELEVANCE: Rapid stabilization of bone remodeling and robust papilla regeneration indicate favorable tissue healing promoted by the conical connection, platform-shift design. TRIAL REGISTRATION: clinicaltrials.gov NCT02175550.

Periodontal-restorative collaboration: the basis for interdisciplinary success in partially edentulous patients.

Restorative dentists are the primary interface between dentistry and the general public. In this capacity, they are increasingly involved in both the placement of implants and the final esthetics of the definitive restorations. With patient demand steadily increasing for implants as single-tooth and multi-unit replacements-often in a compromised periodontium-effective collaborative decision-making between the periodontist and the restorative dentist is more critical now than ever. Inherent disparities between their skillsets--particularly from a surgical stand-point-inextricably link these practitioners as collaborators in preserving and rehabilitating periodontium and dentition alike. The cases described in this article provide insight into how such collaboration enables high-quality interdisciplinary outcomes when replacing teeth with implants in the esthetic zone.

A Prospective Clinical Study on Implant Survival at 1-Year Post-Loading of a Bone-Level Tapered Implant in Private Practice: Multicentered Study.

This non-interventional study evaluated the implant survival and success of a new bone-level tapered implant design in seven private dental practices in the United States. One hundred subjects in need of implant(s) were enrolled according to all cleared indications. After implant surgery, subjects were followed for a period of 1-year post-loading. Treatment planning, implant stability, radiographic evaluation of bone levels, soft-tissue characteristics, clinician satisfaction, and adverse events were assessed. A total of 184 implants were placed, of which 172 were evaluable at 1-year follow-up. Of the 172 evaluable implants, 169 survived and were successful at 1-year post-loading. Of 152 implants with radiographs at 1 year, 90% showed no bone remodeling or <1 mm bone loss. Overall clinician satisfaction was high across all centers. Normal soft-tissue profiles were reported around the implants with improvement in color, form, and mucosal attachment at 1 year. In a "real-world" setting this observational study demonstrated high implant survival and success, stable crestal bone levels, high clinician satisfaction, and a low incidence of adverse events.
