The use of autologous bone for augmentation procedures leads to low prevalence of peri-implantitis-a retrospective study over a 20-year period.

The aim of this study was to compare the prevalence of peri-implantitis in implants inserted into pristine bone (control) to implants where autologous bone was used for grafting procedures (study). All patients who underwent implant surgery during a 20 years interval by one maxillofacial implant surgeon and received a prosthodontic rehabilitation afterwards were eligible for inclusion in the study. Periimplant bone resorption and periimplant disease were assessed.

Status report on dental implantology in Switzerland. An updated cross-sectional survey.

A status report of dental implantology in Switzerland has already been performed in 1994 and 2006. The present study, based on these former surveys, aimed to update these results for the year 2016. To this end, a questionnaire was sent to all dentists in Switzerland who were members of the Swiss Dental Society (SSO) at the time of the survey.

[The Interdisciplinary Stomatology Service at the Department of Oral Surgery and Dental Imaging, University Center for Dental Medicine and the University Hospital Basel, Switzerland - Results from 2003 - 2013].

The Interdisciplinary Stomatology Service at the Department of Oral Surgery and Dental Imaging, University Center for Dental Medicine and the University Hospital Basel, Switzerland - Results from 2003 - 2013 Stomatological problems are common, but rarely diagnosed in private dental practice. Even for oral surgeon's diagnosis and therapy of these disorders could be challenging. Stomatological problems can indicate general health problems.

Fully Digitally Guided Implant Surgery Based on Magnetic Resonance Imaging.

Purpose: The purpose of this study was to evaluate whether fully digitally guided implant surgery may be performed with sufficient accuracy based on printing virtually designed templates after matching a surface scan with the magnetic resonance imaging (MRI) dataset mimicking edentulous cases based on cadaver maxillae of pigs.

Materials And Methods: The palatal mucosa of five young pig cadavers was scanned with an intraoral scanner. High-resolution MRI of the jaws was performed, and the images were exported as DICOM files and uploaded into software for implant planning.

Significance of endothelial progenitor cells (EPC) for tumorigenesis of head and neck squamous cell carcinoma (HNSCC): possible marker of tumor progression and neovascularization?

Objectives: Angiogenesis and neovascularisation plays a crucial role for tumorigenesis and tumor progression in head and neck squamous cell carcinoma (HNSCC). The aim of our study was to investigate the neovascularization capacity by endothelial progenitor cells (EPC) in tumor patient as a possible predictor for tumor progression and tumor stage.

Materials And Methods: Therefore, we investigated the cell number and biologic activity by cell migration and colony-forming ability of EPC.

20 years of cleft lip and palate missions.

Volunteer missions for cleft lip and palate (CLP) care in Indonesia (1991-1992), India (1994-2003), Bhutan (2005-2010), and Kenya (2011), took place always at the same Hospital in each country. Altogether over a thousand patients were operated using a conservative protocol: Safety first - no experiments. Five months and 5 kg were the basic rules.

SADMFR guidelines for the use of Cone-Beam Computed Tomography/ Digital Volume Tomography.

Cone-Beam Computed Tomography (CBCT) has been introduced in 1998. This radiological imaging procedure has been provided for dentistry and is comparable to computed tomography (CT) in medicine. It is expected that CBCT will have the same success in dental diagnostic imaging as computed tomography had in medicine.

Antidepressants relevant to oral and maxillofacial surgical practice.

Background: Depression is commonly associated with a high-carbohydrate diet, lack of interest in proper oral hygiene and xerostomia connected to the use of antidepressants. Patients often consult their dentists as a result of changes affecting the hard dental substance and the soft-tissues.

Aim: The aim of this study was to identify adverse drug interactions between the antidepressants and medications commonly administered in dentistry in order to give practicing dentists an overview of the scientific literature.

Is the Schneiderian membrane thickness affected by periodontal disease? A cone beam computed tomography-based extended case series.

Objective: The aim was to assess the thickness of Schneiderian membranes (SM) in patients with advanced periodontal disease.

Methods: 17 dentate patients (DG) scheduled for periodontal surgery on maxillary molars were consecutively recruited and cone beam computed tomographies performed for preoperative diagnosis. Twenty-one patients (EG) requiring cone beam computed tomography-based planning of implant placement in the edentulous posterior maxilla served as controls.

A prospective noninterventional study to document implant success and survival of the Straumann Bone Level SLActive dental implant in daily dental practice.

Objectives: Clinical studies to assess dental implants are common in implantology, but such studies are usually performed for specific indications and following a specific protocol with strict inclusion and exclusion criteria. The aim of the current study was to evaluate the Straumann Bone Level SLActive dental implant in a prospective, multicenter, noninterventional trial.

Method And Materials: The implant could be used in whatever manner was deemed suitable by the clinician, within approved indications.

Recognizing calcifications of the carotid artery on panoramic radiographs to prevent strokes.

Panoramic radiographs are made routinely in dentistry and are regarded as a standard component of an initial dental examination. Often, these radiographs show opacities in the carotid artery territory (CAT), which frequently arise as a result of calcification in the internal (ICA) or external carotid artery (ECA). This study details the examination of patients with suspected calcifications in the carotid artery (CA), using a sonographic examination based on the panoramic radio graphs to confirm or rule out a possible stenosis in the cervical bloodvessels.

Bisphosphonate-related osteonecrosis of the jaws--a review.

The aim was to evaluate the knowledge about bisphosphonate-related osteonecrosis of the jaws (BRONJ). A bibliographic search in Medline, PubMed and the Cochrane Register of controlled clinical trials was performed between 2003 and 2010 by using the terms bisphosphonate and osteonecrosis of the jaw. The amount of publications per year, the type of journal for publication, and the evidence level of the trial were evaluated.

Thermal conduction of titanium implants under CO2 laser irradiation in vitro.

Objective: The surgical exposure of dental implants can be performed by means of scalpel, punch, or, with less bleeding, by means of CO2 laser. Possible overheating of the peri-implant bone tissue should be avoided. The goal of this study was to examine the temperature changes on implants under CO2 laser irradiation (Luxar CO2 20 SP laser from POLYMED, Glattbrugg, Switzerland).

Cardiovascular monitoring and its consequences in oral surgery.

Objective: Higher life expectancy has lead to an increase of elderly patients in dental practices, thus also causing an increase in high-risk cardiovascular patients.

Study Design: In all, 3012 patients had oral surgery with local anesthesia at the Department of Oral Surgery, Oral Radiology and Oral Medicine at the University of Basel. The Colin BP 306 compact monitor was used during these surgeries.

[Immediately loaded MonoType implants in the edentulous mandible].

Results of immediately loaded implants are presented. 34 patients with 136 interforaminal MonoType implants (Straumann,Basel, Switzerland) were included in the study. The bar retention was manufactured fter the operation, inserted and covered with a hybrid prosthesis.

Oral care.

Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases.

[Soft tissue calcifications in panoramic radiography. A risk factor for cerebrovascular accidents?].

Panoramic radiography is a basic diagnostic tool in the dental field where calcifications are seen occasionally in the lateral parts of the x-ray. The differential diagnosis are carotid artery atheromas, calcified submandibular lymphnodes and sialoliths of the submandibular gland. 4007 panoramic radiographs (100%) from patients >40 years were scanned retrospectively.

[Cervicofacial actinomycosis: two case reports].

Infectious diseases transmitted by actinomycosis species cause severe destructive lesions. This rare and specific infection is mainly found in the orofacial regions. Causes of any hard tissue swelling in the jaw have, thus, to be assessed carefully.

Unifocal Langerhans cell histiocytosis of the oral mucosa.

A 24-year-old man was admitted for a painful gingival ulcer. Histology and immunohistochemistry of a lesional biopsy revealed the diagnosis of Langerhans cell histiocytosis (LCH). To rule out multifocal disease, a complete staging was performed.

Vertical distraction osteogenesis of the alveolar process for implant therapy: two case reports.

Rehabilitation of the chewing function of a patient depends on the quality and volume of the existing jawbone. Vertical augmentation of the jawbone is often a challenge for the dental surgeon. Various transplantation methods, from transplantation of autogenous bone to use of bone substitute material, have been described and discussed and are often controversial.
