REHABILITATION OF A SINGLE ELEMENT IN POSITION 4.6 WITH A PRAMA IMPLANT

This case report presents a clinical result obtained with a new implant morphology. The characteristics of this new implant system make it different from others, due above all to the distinctly extracrestal positioning of the abutment-implant connection and the morphology of the abutment-implant complex neck with a vertical finish area.
The transgingival healing of the implant allows a second surgical operation to uncover the implant to be avoided.
The peri-implant mucosa tissues heal around the machined titanium surface of the implant neck. These tissues no longer need to be stimulated during the various prosthetic phases, making it possible to eliminate some of the modifications to the bone margin caused by repeated screwing and unscrewing operations for prosthetic components.
In addition, by moving the implant-abutment gap away from the marginal bone crest, the peri-implant bone resorption that always occurs in implant methods where this gap is at the level of the bone margin is eliminated.
The vertical finish area of the abutment-implant neck complex allows the emergence morphology of the prosthetic crown to be used to guide the soft tissues and to adapt them to its anatomy. Furthermore, the ferrule effect that can be obtained by covering not only the abutment but also the implant neck with the prosthetic crown could reduce the possibility of biomechanical complications like the slackening or breakage of the post screw.
The clinical result appeared to be positive, both in functional terms and with respect to the integration of the prosthetic crown with the surrounding tissues.

REHABILITATION OF A SINGLE ELEMENT IN AN AESTHETIC AREA WITH A PRAMA IMPLANT

Implant rehabilitations in aesthetic areas always require the greatest care by clinicians, particularly in cases where a post-extraction implant technique is necessary, and even more so in case of immediate loading. In these cases, the preparation of the clinical case is of fundamental importance to allow as much pre-operative information as possible to be obtained, and so that the materials to be used can be studied. In the case described here, it was necessary to use a screwed-in implant that would allow an insertion torque of no less than 50 Ncm to be reached, and that at the same time would give us the possibility to vary the emergence point of the prosthetic profile. allowing us to perform vertical Platform Switching and giving the operator. The PRAMA implant used combines these main characteristics, and also adds surfaces with a high level of biological performance.
Clinical procedures were complicated by the need to perform guided bone regeneration in the vestibular dehiscence as well, requiring particularly accurate soft tissue management, in line with the indications provided in literature for aesthetic cases.
In addition, the temporary crown was supported in the initial phases by a small splint connected to nearby teeth with composite resins.

Having analyzed 47 patients who were users of various commercial implants allocated to a Control Group (healthy) or a Test Group (with peri-implantitis), the authors identified PARVIMONAS MICRA in all Test Group patients. They concluded that PARVIMONAS MICRA could be considered a predictor of peri-implantitis.

One implant was placed in 18 periodontally healthy patients, who were subsequently split into either the control group (abutment cleaned with steam) or the test group (abutment cleaned with plasma of Argon) at prosthetic loading. No significant differences between the two groups in terms of implant survival and success were found after 5 years. However, significant differences in terms of aesthetic outcomes were found between the test group and the control group.

The aim of the clinical study presented in this article, unveiled by the poster presented at EAO 2016 and detailed in the preceding pages, was to compare two different implant emergences: 37 patients were split into two groups according to the type of implant received: Group A (Premium SP Platform-Switching implants) and Group B (Premium TG transmucosal implants). Both implant emergences assessed 12 months after prosthetic loading showed similar survival and clinical characteristics.

In this 24-months study, 30 implants placed in 30 patients immediately after tooth extraction using collagenated cortico-cancellous porcine bone demonstrated 100% survival and no crestal bone reabsorption in 73% of patients, less than 0.5 mm in 20% of patients and a reabsorption from 0.5 mm to 2 mm in the remaining 14%, showing good reliability and predictability.

272 implants were placed in 60 patients immediately after tooth extraction. In 30 patients, the reactive soft tissue was debrided from the extraction site prior to implant insertion. The tissue was left in situ in the remaining 30 patients. After 3 years, all the implants had survived and no significant differences in success parameters were observed.

This study at 1, 3, 8 and 12 weeks the stability of Premium implants inserted in completed osteotomies with piezoelectric preparation was measured by assessing ISQ parameters. The results indicated a good final ISQ value even in implants that at the time of surgery had an initial stability lower than 60, and an implant success rate of 97% was reported at 15 months. The preparation of sites with piezoelectric devices seems to accelerate the achievement of good implant stability.
