[Oral manifestation of a mantle cell lymphoma - a swelling in the buccal mucosa as the initial manifestation of mantle cell lymphoma: a case report].

Lymphomas are malignant neoplasms of mature and immature B-cells, T-cells or NK-cells at various stages of differentiation. They predominantly occur in lymphoid tissues, manifestations in the oral cavity are rare: 3.5% of all oral malignancies are lymphomas.

[Rehabilitation after implant failure in the anterior maxilla: presentation of treatment options].

The present article illustrates treatment options after implant removal (explantation) as a result of peri-implantitis in the anterior maxilla. After explantation of a dental implant in the anterior maxilla, the esthetical as well as functional rehabilitation is a demanding undertaking, especially, if removable prosthetic treatment options are undesirable. The present article illustrates that depending on individual patient's demands, different treatment options might be considered.

[The extrosseous/peripheral ameloblastoma in the aesthetic area of the maxilla: a presentation of a possible approach aiming an aesthetic satisfying rehabilitation. a case report].

Extraosseous/peripheral Ameloblastoma (EPA) is a rare, benign odontogenic soft tissue tumour with the same histological characteristics as the more common intraosseous subtypes. The EPA appears in the soft tissue of the gingiva and the mucosa of the alveolar process often as unspecified painless swelling. The present case report describes an EPA in the aesthetic area of the left anterior maxilla.

[Spontaneous reeruption after intrusive luxation of the permanent incisors by incomplete root formation. Two case reports (in German)].

In the context of tooth trauma mostly the maxillary central front teeth are involved, whereby their roots are in some cases in developing stage (immature). The intrusive luxation represents one of the most severe types of dental trauma because of the damage to the periodontal ligament, alveolar bone and pulp. Principally, three different treatment options are available: 1.

[The dentigerous cyst: two different treatment options illustrated by two cases].

The dentigerous cyst is the second most frequent odontogenic cyst after the radicular one. Typically, dentigerous cysts are asymptomatic and are commonly diagnosed incidentally. Due to the slow, expansive growth dentigerous cysts have the potential for dislocation of adjacent structures (neighbouring teeth, canalis retromolaris), root resorptions and in an extreme case could cause jaw fractures.

[Regenerative endodontics after front tooth trauma. A case report].

In the context of tooth trauma, mostly the maxillary central front teeth are involved, whereby their roots are in some cases still in the developing stage (immature). Depending on the type of trauma, a necrosis of the pulp is the consequence or at least foreseeable. In order to preserve such a tooth, an endodontic therapy is inevitable.

Implant-Assisted Removable Partial Denture Prostheses: A Critical Review of Selected Literature.

Purpose: A critical review of selected relevant publications assessed clinical efficacy and effectiveness of implant-assisted removable partial dentures (IARPDs) with implant survival and failure rates, biologic and technical complications, and maintenance and patient satisfaction after rehabilitation as outcomes.

Materials And Methods: Screening of three databases (Medline [PubMed], Embase [OVID], and the Cochrane Library [CENTRAL]) and a manual search of related articles were performed. Reports on outcomes from human studies conducted between 1 January 1980 and 31 May 2016 were considered.

The Impact of Brief Interventions for Tobacco Cessation on Patients' Awareness of Cigarette Smoking as a Risk Factor for Chronic Periodontitis.

Purpose: To evaluate the awareness of cigarette smoking as a risk factor for chronic periodontitis in patients either undergoing active periodontal treatment (APT) or enrolled in supportive periodontal therapy (SPT).

Materials And Methods: Comprehensive tobacco use history was collected with a questionnaire in 50 patients before and after APT (test) and in 50 patients (control) enrolled in SPT at the School of Dental Medicine, University of Bern. Carbon monoxide (CO) exhalation levels were measured in both APT and SPT patients.

Soft tissue augmentation around osseointegrated and uncovered dental implants: a systematic review.

Objectives: The aim was to compile the current knowledge about the efficacy of different soft tissue correction methods around osseointegrated, already uncovered and/or loaded (OU/L) implants with insufficient soft tissue conditions. Procedures to increase peri-implant keratinized mucosa (KM) width and/or soft tissue volume were considered.

Materials And Methods: Screening of two databases: MEDLINE (PubMed) and EMBASE (OVID), and manual search of articles were performed.

Soft tissue augmentation procedures at second-stage surgery: a systematic review.

Objectives: The aim of this systematic review was to evaluate the efficacy of different soft tissue augmentation/correction methods in terms of increasing the peri-implant width of keratinized mucosa (KM) and/or gain of soft tissue volume during second-stage surgery.

Materials And Methods: Screening of two databases, MEDLINE (PubMed) and EMBASE (OVID), and hand search of related articles, were performed. Human studies reporting on soft tissue augmentation/correction methods around submucosally osseointegrated implants during second-stage surgery up to July 31, 2015 were considered.

[The surgical crown lengthening procedure in order to improve the biological width and esthetics].

The aims of surgical crown lengthening procedures are to improve prosthetic reconstructions at teeth with limited hard tissue, to prevent periodontal problems and/or to improve esthetics. When planning and performing surgical crown lengthening, it is important to consider not only periodontal and technical aspects but also the gingival profile of the neighbouring teeth. This paper presents the systematic approach starting with the diagnosis and indication to the performed treatments and the obtained results and gives clinical recommendations.

Soft tissue grafting to improve the attached mucosa at dental implants: A review of the literature and proposal of a decision tree.

Background: Scientific data and clinical observations appear to indicate that an adequate width of attached mucosa may facilitate oral hygiene procedures thus preventing peri-implant inflammation and tissue breakdown (eg, biologic complications). Consequently, in order to avoid biologic complications and improve long-term prognosis, soft tissue conditions should be carefully evaluated when implant therapy is planned. At present the necessity and time-point for soft tissue grafting (eg, prior to or during implant placement or after healing) is still controversially discussed while clinical recommendations are vague.

The alveolar ridge splitting/expansion technique: a systematic review.

Purpose: The aim of this systematic review was to evaluate clinical, radiological and histological outcomes of the alveolar ridge splitting/expansion technique (ARST) with or without GBR.

Materials And Methods: A screening of two databases MEDLINE (PubMed) and EMBASE (OVID) and hand search of articles were performed. Human and animal studies reporting on dental implants placed with simultaneous ARST up to May 31st 2014 were considered.

[Subcutaneous emphysema following non-surgical peri-implantitis therapy using an air abrasive device: a case report].

Subcutaneous emphysema are rare complications in periodontology. In most cases, they resolve spontaneously. However, air might disperse into deeper facial spaces causing life-threatening complications such as compression of the tracheobronchial tree or the development of pneumomediastinum.

Piezoelectric alveolar ridge-splitting technique with simultaneous implant placement: a cohort study with 2-year radiographic results.

Purpose: Extended grafting procedures in atrophic ridges are invasive and time-consuming and increase cost and patient morbidity. Therefore, ridge-splitting techniques have been suggested to enlarge alveolar crests. The aim of this cohort study was to report techniques and radiographic outcomes of implants placed simultaneously with a piezoelectric alveolar ridge-splitting technique (RST).

Anti-infective therapy of peri-implantitis with adjunctive local drug delivery or photodynamic therapy: 12-month outcomes of a randomized controlled clinical trial.

Objective: The objective of the study is to compare the clinical, microbiological and host-derived effects in the non-surgical treatment of initial peri-implantitis with either adjunctive local drug delivery (LDD) or adjunctive photodynamic therapy (PDT) after 12 months.

Materials And Methods: Forty subjects with initial peri-implantitis, that is, pocket probing depths (PPD) 4-6 mm with bleeding on probing (BoP) and radiographic bone loss ≤2 mm, were randomly assigned to two treatment groups. All implants were mechanically debrided with titanium curettes and with a glycine-based powder airpolishing system.

[Prosthetic rehabilitation of a traumatic occlusion due to bulimia nervosa. Case report].

Because of the typical localisation of erosions in anorectic/bulimic patients, the dentist is frequently the first medical person to discern this general illness (anorexia and bulimia nervosa). From the dental viewpoint, the aim should be to preserve sound dental tissue and to prevent further toothwear. A restorative treatment is to be carried out only after causal therapy and after resolving the basic disease.

[Treatment of advanced peri-implantitis in the mandible].

This case report shows the experimental treatment of a 85 year old female with advanced periimplantitis, the surgical augmentation, the clinical as well as the radiological follow-up until twelve months after surgery. the treatment of the advanced periimplantitis with a three-dimensional vertical defect around the implant consisted of a surgical bone augmentation technique supported by the Air-Flow Master® system (EMS, Nyon, Switzerland).

[Does the combination syndrome exist? A case report].

This case report documents the prosthetic rehabilitation of a patient showing the typical features of combination syndrome. This case documentation gives a general overview of the suspected development and the prevalence of this "syndrome". A treatment option should be shown by the example of a patient from the starting situation until the prosthetic therapy by means of a complete maxillary denture and an implant-supported mandibular overdenture rigidly retained with a milled bar.
