Brian J Jackson
The field of oral Implantology continues to evolve with an emphasis on minimally invasive approaches. Scientific research introduced immediate implant placement and provisionalization (IIPP) over 40 years ago. The approach is a synergy between surgical and prosthetic stages reducing discomfort, appointments, and costs while producing positive outcomes. A dehiscence of the facial plate of bone (type 2 socket) requires clinical modifications to the standard protocol. This paper describes the IIPP protocol for a type II socket and provides a decision tree to utilize as a guide in patient management...

Removal of osseointegrated but otherwise failed (mechanical failure, mispositioning, aesthetics, etc.) dental implants is a traumatic process resulting in loss of healthy bone and complicating the treatment process. The traumatic effects of implant removal can be reduced by weakening the implant-bone attachment. Thermal necrosis-aided implant removal has been proposed as a minimally invasive method towards this end. In this method; an electrocautery tip is contacted to the implant to increase the temperature to 47oC and generate a limited and controlled thermal necrosis at the bone-implant interface...

Sinus floor augmentation (SFA) is the most predictable treatment option in the atrophic posterior maxilla. However, exposure of the apical implant body into the maxillary sinus cavity is an occasional phenomenon after SFA. Although most penetrating dental implants remain completely asymptomatic, they may induce recurrent rhino-sinusitis or implant loss. Despite removal of the implant should be considered if there is significant implant exposure, further treatment duration and costs are required. This case report demonstrates a recovery approach by sinus floor re-augmentation without implant removal in a case with an apically exposed implant into the maxillary sinus cavity...

The design of an implant has a great effect on primary stability. The purpose of this study was to determine the differences in primary stability between straight and tapered Neoss ProActive implants in type I and type III bones using resonance frequency analysis (RFA) and electronic percussive testing (EPT) methods. Fresh cow vertebrae and pelvis were used as models of type 3 and type 1 bone, respectively. Implants of two different designs i.e. straight and tapered Neoss ProActive implants with a thread cutting and forming (TCF) design, both 3...

Adequate bone remodeling may be a primary parameter for long term successful complication-free dental implant treatment. A 1.8mm osseous thickness around dental implants is thought to be the minimum thickness for adequate vasculature for osteocyte nutrition and function. A dental implant does not provide progenitor cells or angiogenic or osteogenic factors. Thus, the surrounding bone may need to have a 1.8mm thickness to accommodate the vasculature necessary for nutrients for appropriate remodeling. Additionally, the 1...

Early and effective integration of titanium- based materials into bone tissue is of vital importance for long term stability of implants. Surface modification is commonly used to enhance cell-substrate interactions for improving cell adhesion, proliferation and activity. Here, the surface of titanium substrates and commercial implants were coated with blood (TiB), fetal bovine serum (TiF) and phosphate buffer saline (TiP) solution using spin coating process. Surface roughness and wettability of samples were measured using contact angel measurements and atomic force microscopy...

Porous tantalum trabecular metal (PTTM) has long been used in orthopedics to enhance neovascularization, wound healing, and osteogenesis; recently it has been incorporated into titanium alloy dental implants. However, little is known about the biological responses to PTTM in the human oral cavity. We hypothesized that, compared to conventional titanium alloy; PTTM had greater expression of genes specific to neovascularization, wound healing, and osteogenesis during the initial healing period. Twelve subjects required at least four implants in the mandible were enrolled...

Sotos syndrome it is usually transmitted by autosomal dominant inheritance. It is characterized by overgrowth with advanced bone age, macrocephaly, characteristic facial appearance, and learning difficulties. Mandibular prognathism, agenesis, and high-arched palate are the most common oral findings. The treatment of a 28-year-old man with Sotos syndrome is reported. Patient had many dental absences, both in maxilla and mandible. The growth phase had ended and the study of the morphology and bone availability through a bimaxillary cone beam computed tomography was performed...

To perform safe implant treatment, the anatomical structure and bone quality at implant placement sites are evaluated based on a patient's CT data, but there is no definite method to determine placement sites and the appropriate number of implants. The objective of this study was to investigate the influence of the number and arrangement of implants on the stress distribution in 3-unit posterior fixed partial dentures for the posterior mandible by mechanical analysis using the finite element method. Three-dimensional finite element analysis models were constructed from the CT data of a patient with missing mandibular teeth (Nos...

Because of its importance in the development of peri- implant mucositis and peri-implantitis, residual excess cement (REC) detection is often the focus of studies addressing cement-retained implant-supported restorations. The purpose of this study was to evaluate the sensitivity and specificity of laser fluorescence (DIAGNOdent) for detecting residual excess ZnO-based cement around dental implants. In this in- vitro study, 15 tissue level implants were embedded in acrylic resin. To simulate gingiva around the implants, the trans-gingival part of each implant was covered with gingival mask silicon material...

Sixteen patients with a diagnosis of peri-implantitis in 19 of 64 implants (29.7 %) were treated with an open flap approach according to a refined standardized surgical protocol. Treatment consisted of mechanical debridement, application of chemotherapeutical agents, and photodynamic therapy. Bone defects were filled with autologous and allogeneic bone, and subsequently covered with a collagen membrane and a Platelet rich in growth factors fibrin membrane. After a mean follow-up of 36.1 months, none of the treated implants was lost...

The longevity of an immediate implant placement in a molar area with the flapless extraction technique has not yet been deeply investigated, and only a few studies have previously been published. This article describes a successful case of immediate implant placement with a follow-up evaluation after more than five years. An immediate implant was placed in a fresh socket after an atraumatic extraction with no flap elevation. When measured with a periodontal probe, the distances between the implant and socket wall were as follows: buccal, 5mm; proximal, 4mm; and lingual, 3mm...

One of the most important concerns during posterior mandibular implant placement is avoiding the mandibular canal. Nerve injury can be very disturbing to the patient, possibly causing mild paresthesia to complete anesthesia. Explantation of a dental implant that gas violated the mandibular canal is the most recommended treatment. However, an osseointegrated implant that placed in the mandibular canal can be left if the patient shows no symptoms. In this case report, we describe a technique to maintain the apexes of the implants while partially removing fractured osseointegrated implants previously placed in the mandibular canal...

Platelet-rich fibrin is a blood concentrate system used for soft tissue and bone tissue regeneration. In the last decade, platelet rich fibrin (PRF) has been widely used in different indication fields, particularly in oral and maxillofacial surgery. This review investigates the level of scientific evidence of published articles related to the use of PRF for bone and soft tissue regeneration in dentistry and maxillofacial surgery. An electronic literature research using the biomedical search engine "National Library of Medicine" (PubMed-MEDLINE) was performed in May 2017...

Local delivery agents are widely used in peri-implantitis treatments. The aim of this study was to identify local delivery agents remaining on the dental implant surfaces and to analyze the components of these residues after applying various cleaning methods. Implants were prepared with a sand-blasted, large-grit, acid-etched surface. Four kinds of local delivery agents were applied on the implant surfaces: chlorhexidine gel (group 2), tetracycline solution (group 3), and two kinds of minocycline hydrochloride agents (groups 4 and 5)...

Osteonecrosis of the jaw is a rare complication that have been associated with the use of bisphosphonates (BP). A 77 years old patient presented in April 2013 asking for a consultation. She reported that in May 2009, she underwent an implant rehabilitation with 8 implants and an immediately loaded fixed prosthesis in the maxilla. After few months the patient started to report pain and purulent secretions, that were neglected by the clinician for several years. She decided to refer to the Dental Clinic after another acute pain episode...
