Twenty eight months marginal bone level follow-up of an immediate post-extractive implant with immediate definitive loading.

Objective: The aim of this case report was to show the marginal bone level (MBL) variation, after 28 months, around an aesthetic post-extraction implant immediate loading positioned in a 46-years-old woman.

Material And Methods: After a careful evaluation of the X-rays and CBCT images, a 4×13 conical implant was placed in seat 21 after the atraumatic extraction of the fractured element and the management of the infected area. Correct primary stability (torque 70 Ncm) was obtained by inserting the implant in a palatal position with respect to the alveolus.

Continuous craniofacial growth in adult patients treated with dental implants in the anterior maxilla.

Background: In the Literature, there are several studies demonstrating that infraposition happens also in adult patients.

Purpose: To conduct a retrospective evaluation of infraocclusion of implant-retained crowns in the anterior maxilla of adult patients and of the patient awareness and perception of the problem.

Material And Methods: From January to June 2017, all adult patients who in the last 5 to 20 years had received in the same clinic implant restorations in the upper anterior maxilla were recalled to assess the presence of crown infraocclusion.

Comparison of a Novel Ultrasonic Scaler Tip vs. Conventional Design on a Titanium Surface.

The aim of this in vitro study was to evaluate the alterations of a titanium surface after treatment with two different types of ultrasonic tips: conventional steel versus an innovative copper alloy silver-plated one. Twenty smooth-surface, grade IV unalloyed titanium discs were divided into two groups. The discs were ultrasonically instrumented and the scaler was connected with a loading machine.

Infraposition of Implant-Retained Maxillary Incisor Crown Placed in an Adult Patient: Case Report.

Several studies have clearly shown that osseointegrated implants, when inserted in growing bone, such as in adolescents, do not follow the eruptive path of adjacent teeth; instead, they act like ankylosed teeth, remaining in a stationary position for the lifetime, thus developing a progressive infraposition of the implant-supported crown. However, further studies have demonstrated that similar changes also occur in adult patients, although mostly in a small amount and over long time spans. Here the case of a female patient aged 35 years is presented, in which infraposition of the maxillary central incisor developed in a very short time (15 months).

Lateral Sinus Floor Elevation Performed with Trapezoidal and Modified Triangular Flap Designs: A Randomized Pilot Study of Post-Operative Pain Using Thermal Infrared Imaging.

Post-operative pain and swelling are frequently observed after sinus lift procedures. The aim of the present study was the clinical evaluation of swelling and pain of two different sinus flap lift techniques using a visual analogue scale (VAS), verbal rating scale (VRS), and infrared thermal imaging (i.e.

Instant loading with intraoral welding technique and PRAMA implants: a new prosthetic approach.

When splinting multiple implants passive fit of the framework should be achieved to avoid excessive force distribution on the implants. Recently, a protocol was suggested for immediate loading of multiple implants by welding a titanium bar to implant abutments directly in the oral cavity so as to create a customized, precise and passive metal-reinforced provisional restoration. The intraoral welding technique subsequently proves to be a successful option in the full-arch immediate restorations of the mandible and maxilla.

Static and fatigue resistance of two types of implant/abutment connectors.

The aim of this study is to determine in an experimental way through mechanical tests the static, fatigue and torque resistance of two types of implant/abutment connectors with diameters of 3.4–5.2 mm.

Biomechanical considerations on macromorphology of endosseous dental implants.

The aim of the present study is to define the optimal thread form and why the macroscopic shape of the dental intra-osseous implant interacts with the biological environment thus conditioning its lifespan and long-term success.

The use of cortical heterologous sheets for sinus lift bone grafting: a modification of Tulasne's technique with 7-year follow-up.

In this article, the authors describe their experience with using cortical deantigenated equine bone sheets in sinus lift grafting procedures performed on 23 patients. The technique employed resembles that described by Tulasne but avoids the need for using harvested calvaria bone and introduces some additional operating variants. The use of heterologous cortical bone sheets effectively managed even large lacerations of the Schneiderian membrane and allowed for immediate stabilization of the heterologous bone granules.

Microbiologic evaluation of crevicular fluid in patients treated with platform switching and traditional implants.

Background: The purpose of this study was to compare the microbiota around natural teeth and dental implants with different restorative platforms. Attention was focused on whether the microbiological environment could change according to the implant platform used i.e.

Vertical ridge augmentation using a flexible heterologous cortical bone sheet: three-year follow-up.

Rehabilitation of the atrophic alveolar ridge is often problematic. Bone augmentation surgery may be hindered by a lack of surfaces from which blood vessels can spread during the initial stages of bone regeneration. If heterologous biomaterials are used as an alternative to autologous bone grafts, the standard delivery formats-blocks or granules-both have significant limitations.

The abutment duplication technique: a novel protocol for cementable implant-supported restorations.

The purpose of this study was to present a new laboratory technique for cementable implant-supported restorations and to evaluate its efficacy in reducing chair time for both patients and clinicians, while maintaining the precision of an indirect procedure for crown fabrication. The technique consisted of the duplication of the implant portion of a working cast prepared using double-pour or plastic base die systems for single or multiple crowns. For this purpose, a flask previously intended for the production of ceramic inlays and onlays was used.

Evaluation of hard tissue response around wider platform-switched implants.

The use of a narrower-diameter abutment over a larger-diameter implant platform has been shown to decrease peri-implant bone resorption. This technique, known as platform switching, shifts the implant-abutment microgap inward. The aim of this study was to examine whether shifting the microgap further inward by increasing the discrepancy between the implant platform and abutment diameter would result in a decrease in crestal bone loss.

The use of piezosurgery to mobilize the mandibular alveolar nerve followed immediately by implant insertion: a case series evaluating neurosensory disturbance.

One of the therapeutic options proposed for reconstruction of the atrophic posterior mandible is inferior alveolar nerve (IAN) mobilization with simultaneous implant placement. However, studies on the functionality of this neurovascular bundle after its mobilization have shown mixed results. This variability can be attributed both to the test methodology, which typically requires subjective answers from patients, and to the surgical procedure itself, which is highly dependent on operator technique.

alpha-Defensin levels in whole saliva of totally edentulous subjects.

Salivary levels of alpha-defensins 1-4 and histatins 1, 3 and 5 were determined in 11 totally edentulous patients, 11 younger healthy adults with normal gingival mucosa (Control group I) and 8 subjects, age-matched with edentulous patients, having a minimum of 25 teeth (Control group II). Whole saliva was treated with trifluoroacetic acid and the acidic soluble fraction analyzed by High Performance Liquid Chromatography-Mass Spectrometry. The area of the extracted ion current peaks was used for peptide quantification.

Evaluation of peri-implant bone loss around platform-switched implants.

This clinical and radiographic prospective study evaluated bone loss around two-piece implants that were restored according to the platform-switching protocol. One hundred thirty-one implants were consecutively placed in 45 patients following a nonsubmerged surgical protocol. On 75 implants, a healing abutment 1 mm narrower than the implant platform was placed at the time of surgery.

Bone contact around osseointegrated implants: histologic analysis of a dual-acid-etched surface implant in a diabetic patient.

The clinical applicability and predictability of osseointegrated implants in healthy patients have been studied extensively. Although successful treatment of patients with medical conditions including diabetes, arthritis, and cardiovascular disease has been described, insufficient information is available to determine the effects of diabetes on the process of osseointegration. An implant placed and intended to support an overdenture in a 65-year-old diabetic woman was prosthetically unfavorable and was retrieved after 2 months.

Alveolar ridge augmentation using membranes.

Successful augmentation of compromised ridges using membranes requires correct diagnosis and careful case selection. The goals of the reconstruction should be identified before surgery. The timing and application of membranes and selecting the type of bone graft specific for each site are important.

Bone contact around osseointegrated implants: a histologic study of acid-etched and machined surfaces.

Three-stage approach to aesthetic implant restoration: emergence profile concept.

Proper treatment planning and precise evaluation of various parameters (e.g., bone volume, soft tissues, dental anatomy, surgical and prosthetic components) are crucial for an aesthetic implant restoration.

Optimal implant stabilization in low density bone.

Initial stability of the implant is one of the fundamental criteria for obtaining osseointegration. An adequate primary anchorage is often difficult to achieve in low density bone (type IV). Various surgical suggestions were advanced in the 1980s which were aimed at achieving optimal osseous integration in poor quality bone.
