Abstract

Objective The aim of this research is to observe and evaluate the clinical application of the Esthetic Line [EL] implant system (C-Tech, Bologna, Italy). The EL implant has a surface topography created by sandblasting and acid etching (SLA) and a Morse locking conical connection.

Methods 35 patients with one or more missing teeth were selected and a total of 60 EL implants were placed using either a one stage (non-submerged) placement protocol or a two stage (submerged) protocol. Where applicable, second stage surgery was undertaken 2 ~ 4 months post implantation. Subsequent to this the EL implants were permanently restored over a period of 2 ~ 4 weeks. Clinical examination and imaging analysis were undertaken to evaluate clinical success.

Results All 60 implants osseointegrated successfully, and at the one year follow up there was a 100% retention rate and no adverse reactions in the host. Mesial and distal bone heights were recorded on the day of surgery as well as at the fitting of the permanent restoration and after the implants had been functionally loaded for 12 months. Mesial bone heights were (0. 35 ± 0. 49) mm, (0. 18 ± 0. 44) mm and (0. 25 ± 0. 36) mm respectively. Distal bone heights were (0. 20 ± 0. 42) mm, (0. 08 ± 0. 45) mm and (0. 15 ± 0. 38) mm. In the first year of implant functional load, the total absorption of the mesial bone was (- 0. 11 ± 0. 38) mm and the distance was (- 0. 07 ± 0. 31) mm; There was no significant difference in blood indexes between the preoperative and postoperative three months (P < 0. 05).

Conclusion The design of the EL implant incorporating a combination of a parallel walled section with an apical taper, a beveled shoulder, platform switching, a Morse locking conical connection combined with an SLA treated surface and a sophisticated double threaded morphological design all contribute to successful treatment.

Key words Italy; C – Tech Esthetic Line [EL] implant; implant design; surface treatment; Morse-locking.

In recent years, the evolution of implant techniques combined with developments in implant design and restorative techniques has resulted in greater acceptance of implant treatment by the majority of patients. The Stomatology department of our hospital has adopted the Esthetic Line [EL] implant system (C-Tech, Bologna, Italy) for use in our clinic. A study into the clinical results of 60 EL implants placed in 35 patients was undertaken.  

Conclusions

To sum up, the innovative design of the Esthetic Line implant with its sequential thread design, micro-threads to preserve bone at the collar, sophisticated self-cutting and double lead threading preserves bone structure and increases bone to implant contact. This is combined with a SLA surface treatment, a combination of a bevelled shoulder with a platform switching design and a Morse locking conical connection to make it safe and effective in clinical application. The limitation of this study is that the number of cases included is relatively small, only 30 implants of 35 patients were followed up for 12 months. More accurate clinical effect requires more long-term retrospective and prospective clinical observation and research on larger sample size.

Investigation of peri-implant tissue conditions and peri-implant tissue stability in implants placed with simultaneous augmentation procedure: a 3-year retrospective follow-up analysis of a newly developed bone level implant system

Jonas Lorenz University Hospital Frankfurt · Department of oral, maxillofacial and plastic surgery, Henriette Lerner HL DENTCLINIC, Robert A. Sader Goethe-Universität Frankfurt am Main · Center of Stomatology
and Shahram Ghanaati Goethe University of Frankfurt/Main; Universitätsmedizin der Johannes Gutenberg-Universität Mainz · Department for Oral, Craniomaxillofacial and Facial Plastic Surgery; Institute of Pathology

The aim of the present retrospective analysis was to assess peri-implant tissue conditions and document peri-implant tissue stability in C-Tech implants when placed simultaneously with a GBR (Guided Bone Regeneration) augmentation procedure.

A total of 47 implants, which were placed simultaneously with a GBR (Guided Bone Regeneration) procedure with a synthetic bone substitute material in 20 patients, were investigated clinically and radiologically at least 3 years after loading.

The follow-up investigation revealed a survival rate of 100% and only low median rates for probing depths (2.7 mm) and BOP (bleeding on probing) (30%). The mean PES (Pink Esthetic Score) was 10.1 from the maximum value of 14.
No osseous peri-implant defects were obvious, and the mean bone loss was 0.55 mm.

In conclusion, implants placed in combination with a GBR (Guided Bone Regeneration) procedure can achieve long-term stable functionally and esthetically satisfying results for replacing missing teeth in cases of atrophy of the alveolar crest.

School of Dental Medicine University of Belgrade, Serbia – November 2015 – Clinical outcomes following horizontal ridge augmentation with bone block grafts

Clinical outcomes following horizontal ridge augmentation with bone block grafts

Assoc Prof Dr Snezana Colic (School of Dental Medicine University of Belgrade, Serbia)

The aim of this study was to analyze clinical outcome of horizontal augmentation with autologous bone block grafts for the reconstruction of narrow edentulous ridge before implant placement. Eighteen partially edentulous patients, presenting insufficient bone width (less than 4mm) in the sites for implant placement were selected.
One or multiple cylindrical block grafts were harvested with trephine burrs from retromolar region and stabilized with titanium miniscrews. Fixed grafts were covered with deproteinised bovine bone mineral granules (DBBM) and collagen membrane (CM). The average amount of bone gain was 3,6 mm. One of the 24 block grafts was lost during the early healing period. Five months later, during the re-entry for implants placement, the gain of ridge width obtained were measured. All implants were placed in correct position and considered successfully integrated during the observation period. Three month after the implant placement prosthetic rehabilitation was started.
The mean follow up after prosthetic load has been 25,4 months.

This technique is reliable means for the correction of narrow edentulous ridge. Close contact between the bone graft and recipient bed surface ensure fast and intense vascularization and subsequent osseointegration of the graft. Adding bovine bone mineral and collagen membrane over bone block minimize resorption during healing.
In all cases all planned implants could be placed in the correct positions.
The mean duration of follow up of the implants was 25,4 months. Prosthodontics rehabilitation involved single crowns or bridges.
Not a single implant was lost during the observation period. All implants were successful both aesthetically and functionally.
