Single tooth implant restorations in the aesthetic area are a demanding challenge. If a complete osseointegration is mandatory, the final result has to result in a higher standard of biomimetic and soft tissue health among natural teeth. This outcome is traditionally pursued by cementing crowns over individualized abutments. However, in recent years, the need for controlling peri-implant health and the preference towards a retrievable solution has led to an increase in screw-retained crowns, which is not always applicable when the implant axis is not ideal. In the aesthetic area, the use of a novel technical solution represented by the angled screw channel (ASC) of the abutment has been proposed in order to match the advantages of the screwed solution with the aesthetic demands. The aim of this study was to compare ASC crowns to cemented crowns (CC) in single implant restorations using the white esthetic score (WES) and pink esthetic score (PES) at the crown delivery and at a follow-up of a minimum of 2 years. Peri-implant health and marginal bone loss (MBL) were also evaluated. The mean follow-up was 44.3 months, with a mean MBL of 0.22 mm in the ASC group and 0.29 mm in the CC group. The total WES/PES score was 16.6 for ASC, compared with 17.3 for CC at baseline, and 16.2 and 17.1, respectively, at follow-up. Both of the groups reached a high WES/PES, and this was maintained over time, without signs of peri-implant diseases or bone loss, regardless of the choice of connection. In conclusion, ASC can be adopted in cases where the implant axis is not ideal, with aesthetic and functional results that are comparable to implants restored by cemented crowns.

Aim. To compare the outcome of digital versus analog procedures for the restoration of single implants. Methods. Over a two-year period (2014-2016), all patients who had been treated in a dental center with a single implant were randomly assigned to receive either a monolithic zirconia crown, fabricated with digital workflow (test group), or a metal-ceramic crown, fabricated with analog workflow (control group). All patients were followed for 1 year after the delivery of the final crown. The outcomes were success, complications, peri-implant marginal bone loss (PIMBL), patient satisfaction, and time and cost of the treatment. Results. 50 patients (22 males, 28 females; mean age 52.6±13.4 years) were randomly assigned to one of the groups (25 per group). Both workflows showed high success (92%) and low complication rate (8%). No significant differences were found in the mean PIMBL between test (0.39±0.29mm) and control (0.54±0.32mm) groups. Patients preferred digital impressions. Taking the impression took half the time in the test group (20±5min) than in the control (50±7min) group. When calculating active working time, workflow in the test group was more time-efficient than in the control group, for provisional (70±15min versus 340±37min) and final crowns (29±9min versus 260±26min). The digital procedure presented lower costs than the analog (€277.3 versus €392.2). Conclusions. No significant clinical or radiographic differences were found between digital and analog procedures; however, the digital workflow was preferred by patients; it reduced active treatment time and costs. The present study is registered in the ISRCTN (http://www.isrctn.com/ISRCTN36259164) with number 36259164.

The aim of this study was to compare the esthetic outcome of single implants placed in fresh extraction sockets with those placed in fully healed sites of the anterior maxilla. This retrospective study was based on data from patients treated with single-tooth Morse taper connection implants placed in fresh extraction sockets and in fully healed sites of the anterior maxilla. Only single implant treatments were considered with both neighboring teeth present. Additional prerequisites for immediate implant treatment were intact socket walls and a thick gingival biotype. The esthetic outcome was objectively rated using the pink esthetic/white esthetic score (PES/WES). The Mann-Whitney U test was used to compare the PES and the WES between the 2 groups. Twenty-two patients received an immediate implant, and 18 patients had conventional implant surgery. The mean follow-up was 31.09 months (SD 5.57; range 24–46) and 34.44 months (SD 7.10; range 24–48) for immediately and conventionally inserted implants, respectively. No implants were lost. All implants fulfilled the success criteria. The mean PES/WES was 14.50 (SD 2.52; range 9–19) and 15.61 (SD 3.20; range 8–20) for immediately and conventionally placed implants, respectively. Immediate implants had a mean PES of 7.45 (SD 1.62; range 4–10) and a mean WES of 7.04 (SD 1.29; range 5–10). Conventional implants had a mean PES of 7.83 (SD 1.58; range 4–10) and a mean WES of 7.77 (SD 1.66; range 4–10). The difference between the 2 groups was not significant. Immediate and conventional single implant treatment yielded comparable esthetic outcomes.

Aim: Aim of this study was the evaluate the retention and biting force of conventional complete denture and after placement of a single implant in the mandible for an implant retained over-denture Material and methods Eight completely edentulous patients were selected. A single implant was inserted at the symphysis of the mandible and left to osseointergrate. During the osseointegration period a conventional complete denture was fabricated and inserted. Retention and biting force was measured at insertion and after 3 months of service. After osseointegration attachment was connected, space was formed in the fitting surface of the existing mandibular denture and retention silicon was placed. Retention and biting force were measured at insertion and after 3 months follow-up. Data were collected and statistically analyzed. Results: The retention mean values for the complete denture was 2.420±0.360, however the retention mean values for the single implant over-denture was 6.395±0.289.  F=3.80 with statically significance difference between the groups of P <0.01. The biting force mean values for the complete denture was 52.62±2.71, however the biting force mean values for single implant over-denture was 71.45±2.73. F= 1.790 with statically insignificance difference between the groups of P >0.01 Conclusion: Single implant overdenture improved the retention and the biting force when compared with the complete denture, this has improved the quality of life and happiness.

ABSTRACT Aim The aim of this prospective cohort study was to evaluate the postinsertion posterior single-implant occlusion changes at 3- and 6-month intervals using T-Scan computerized occlusal analysis. Materials and methods A total of 21 patients received single implant, opposed by natural dentition, in posterior regions of the maxilla or mandible (13 premolar, 8 molar) and were finally restored with cemented-retained metal–ceramic crowns. The occlusal contacts were equilibrated according to the implantprotective occlusion concept to develop light contact with heavy occlusion and no contact with light occlusion in maximum intercuspation. The percentage of force applied to the implant crowns (POFI) and contralateral teeth (POFT) was evaluated using T-Scan computerized occlusal analysis at prosthesis insertion, 3- and 6-month follow-up appointments. The data were statistically analyzed using Friedman test and Wilcoxon post hoc test (α = 0.05). Results The POFI values at the 6- and 3-month follow-up appointments were significantly higher than those at prostheses insertion (p = 0.001 and p = 0.005 respectively). In addition, there were significant differences between the POFI at 3- and 6-month follow-up (p = 0.020). However, the POFT values at 3- and 6-month follow-up appointments were significantly lower than those at baseline (p<0.001). Conclusion The intensity of occlusal contacts of implantsupported prostheses opposed by natural dentition increased after prosthesis insertion. Placement of single posterior implant-supported restoration decreased the percentage of occlusal force applied to contralateral arch. Clinical significance A periodic occlusal adjustment of implant-supported prostheses is necessary to prevent potential overloading from the movement of opposing natural dentition.

Abstract Objectives To compare the changes in implant stability for the nonsubmerged and submerged protocols for a single-implant retained mandibular overdenture using Cendres and Metaux Locator attachment throughout a 24-month follow-up. Materials and Methods Eighty edentulous patients who were seeking to install a single implant in the midline of the completely edentulous mandible. At the day of implant installation, patients were randomized into two groups using sealed envelopes: the nonsubmerged and submerged groups. After 3 months of healing period, randomization using sealed envelopes was performed and patients were randomized to receive the Cendres and Metaux Locator attachment. The periotest readings were recorded using the Periotest M device, every 3 months for the first year and annually in the second year. The scope of this clinical trial focused only on results of the Cendres and Metaux attachment. Statistical Analysis The Mann–Whitney U-test was used for comparison between study groups for independent samples. Two-sided p-values less than 0.05 were considered statistically significant. Results There was no statistically significant difference between the mean periotest readings of both groups throughout the 24-month follow-up. Both groups showed an improvement in mean periotest readings with the submerged group tending to show greater stability at 6, 12, and 24-month follow-ups. Conclusions The nonsubmerged and the submerged healing protocols resulted in reliable periotest readings with the submerged group showing greater improvement than the nonsubmerged, although this improvement is nonsignificant when using the Cendres and Metaux attachment for a single mandibular overdenture.

Objective The purpose of this study was to retrospectively evaluate the complications and long-term outcomes of total hip arthroplasty (THA) using a hybrid cementless system. Materials and Methods Medical records of dogs that underwent THA using a combined implant system consisting of Innoplant Screw Cup, Kyon taper head and Zurich cementless (Z-THA) stem between March 2010 and March 2015 were reviewed. Dogs with a minimum follow-up of 2 years were included. Signalment, complications and outcome at the latest follow-up examination were recorded. Results Sixteen hybrid THA were performed in 12 dogs. Mean follow-up was 42.5 months. Overall complications occurred in three arthroplasties (19%) including luxation (n = 1), aseptic cup loosening (n = 1) and implant failure with screw breakage followed by stem subsidence (n = 1). Two arthroplasties including prosthesis luxation and aseptic cup loosening were successfully revised using the here described hybrid system and achieved full functional outcome at the last follow-up examination. One arthroplasty with screw breakage and secondary stem subsidence was treated conservatively and achieved an acceptable outcome. Conclusion Hybridization of the Innoplant Screw Cup, Kyon taper head and Zurich cementless for initial THA surgery is feasible. In comparison with the reported complications and outcomes for single implant THA systems, the hybrid THA did not prove to have greater clinical benefits for use in primary THA surgery.
