“…Our study found that the mid‐buccal mucosal level (recession of 0.08 mm, SD 0.20) and interproximal gingival papillae remained relatively stable between Year 1 and Year 5. This is similar to other studies which also showed minimal changes affecting peri‐implant tissues around single implant crowns when dealing with healthy subjects . However, the reported changes in the soft tissue are very small and within the expected measurement error of using a digital caliper.…”

“…Marginal bone levels around these oral implants remained stable especially between Year 1 and Year 5. Another study, including our earlier publication which reported short‐term 1‐year outcomes of these novel implants with a 12° angulated platform, found changes in the marginal bone levels comparable to standard regular‐diameter implants placed according to similar surgical and loading protocols . Our initial 1‐year results involving the original 27 participants showed bone fill of 0.8 mm during the 8 weeks of healing period prior to the baseline measurement.…”

“…The advantages claimed for this design include enhanced thread engagement into the palatal wall and high primary stability following immediate placement into an extraction socket, along with reorientation of the screw access to the palatal side of the prostheses to facilitate screw‐retained restorations. To date, clinical data supporting this system is limited to outcomes after only 1 year of loading …”

Background Single implant crowns have become the preferred rehabilitation treatment option for replacing a missing tooth. Purpose This study evaluates 5‐year clinical success of using tilted implants placed immediately after extraction followed by rehabilitation with all‐ceramic crowns. Materials and Methods Twenty‐seven participants requiring 28 single implant crowns in the aesthetic zone of maxilla were recruited to participate in a single‐arm clinical trial. All participants were rehabilitated according to immediate implant placement using CP grade 4 titanium implants with roughened surfaces and a 12°‐angled platform. Provisional implant crowns were connected within 4 hours of implant placement and loaded according to progressive loading protocol. At 8 weeks (baseline), definitive screw‐retained crowns fabricated using densely sintered zirconia abutments with the veneering porcelain were delivered. Participants were followed up to 5 years and 16 participants with 17 single implant crowns attended Year 5 recall. Data collection included changes in marginal bone levels (MBLs), mid‐buccal mucosal levels (MBMLs), implant stability quotient (ISQ) values, and any prosthodontic maintenance issues. Results The mean changes in MBLs at each recall was bone fill of 0.5 ± 1.18 mm (surgery—baseline), increase of 0.1 ± 0.57 mm (baseline—Year 1), and marginal bone loss of 0.1 ± 0.25 mm (Years 1‐5). A minimal change occurred with the MBMLs during the observation period. The mean ISQ value at each time point increased from 65.1 (implant placement), to 67.4 (baseline) and 69.9 (Years 1 and 5). Prosthodontic maintenance issues occurred only during the first year which included fracture of veneering ceramic and zirconia abutment as well as aesthetic concerns. Conclusions Within the limitations of this study, the data collected would suggest that replacing a single missing tooth using titanium oral implants with 12° platform tilt and zirconia abutments can be a successful rehabilitation option in the esthetically demanding zone of anterior maxilla.

“…Studies conducted by Brown and Payne[6] and Vandeweghe et al . [7] report the successful use of these novel implants for immediate replacement and immediate restoration of single teeth in the esthetic zone, but they are short-term studies with only 1 year of follow-up time. These implants are currently being used for both single and multiunit fixed and removable implant restorations.…”

Implant-supported removable dental prostheses may be supported by a variety of splinted (bar and clip) attachment systems or nonsplinted abutment-based attachments (ball, magnets, and resilient stud attachments such as locators [Zest Anchors], ERA [Sterngold], and nonresilient-stud attachments such as ANKYLOS SynCone [Dentsply Implants]). Nonsplinted attachments are preferred as they are more economical, less technique sensitive, easier to clean, repair, and maintain than splinted (bar and clip) attachment systems, but they work favorably only when implants in the arch are placed parallel to each other. Often implants in the anterior maxilla have to be placed with a labial inclination (due to the proclination of the premaxilla), resulting in lack of parallelism between the anterior and posterior implants, making it challenging to fabricate a removable dental prostheses supported by nonsplinted attachments, and necessitating the use of angled abutments. Recently, a novel implant design with a 12° restorative platform angulation has been introduced by Southern Implants (Co-axis, Keystone Dental, Inc., Burlington, MA, USA). These new angulated implants aid in minimizing the divergence between the anterior and posterior maxillary implants without using angled abutments. The purpose of this article was to report a case utilizing the novel angulated implants (Co-axis, Keystone Dental, Inc., Burlington, MA, USA) in the premaxilla for fabrication of maxillary removable dental prostheses supported and retained by nonsplinted attachments.
