[Neurological emergency after dental implantat insertion - what now?].

The following case report presents a 37-year old male patient who was referred for an emergency assessment due to suspected neurovascular damage of the inferior alveolar nerve following placement of two implants in the posterior left mandible. Immediate explantation for nerve decompression is essential combined with supportive analgesic and antiphlogistic medication. Furthermore, oral glucocorticoids were prescribed, starting with 20mg with a stepwise phasing out of the medication thereafter.

[Peripheral giant-cell granuloma in peri-implant tissues].

Peripheral giant cell granuloma (PRZG) is a locally reactive, non-neoplastic oral tissue proliferation. Histologically, the peripheral form is indistinguishable from the rarer central form of RCC in the jaw area. PRZG usually occur on the gingiva, but are occasionally also found on the palate and the alveolar ridge of the edentulous jaw, very rarely also in the peri-implant tissue.

[Persistent nasopalatine duct: a diagnostic challenge].

The nasopalatine duct (DNP) originates within the nasopalatine canal from epithelial remnants and then develops into an epithelialized connection that extends from the oral cavity to the nasal cavity. Normally, the DNP closes or degenerates in humans before birth. If the DNP persists after birth, oral openings may appear bilaterally, unilaterally or centrally.

Squamous Cell Carcinoma of the Gingiva Mimicking Periodontal Disease: A Diagnostic Challenge and Therapeutic Dilemma.

A case of squamous cell carcinoma of the gingiva (GSCC) in the left anterior maxilla in a 64-year-old woman that was treated for almost 5 years as suspected periodontal lesion prior to establishing the final diagnosis of oral cancer is presented in this case report. GSCCs have a variable clinical appearance, ranging from an exophytic mass to ulcerative lesions. They have been reported to pose a diagnostic challenge and are not infrequently initially misdiagnosed as periodontal disease.

A randomized controlled clinical multicenter trial comparing the clinical and histological performance of a new, modified polylactide-co-glycolide acid membrane to an expanded polytetrafluorethylene membrane in guided bone regeneration procedures.

Objectives: To compare the clinical and histological outcomes of a resorbable modified polylactide/polyglycolide acid (PLGA) test membrane and a titanium-reinforced expanded polytetrafluorethylene (ePTFE) control membrane used for guided bone regeneration (GBR) around dental implants.

Materials And Methods: A total of 40 patients with peri-implant dehiscence-type defects were randomly allocated to a GBR procedure using either a modified PLGA test or an ePTFE control membrane. Soft tissue condition, implant integration, adverse events and quality of life were recorded during the 6-month healing period.

Implants in the esthetic zone.

Over the last 15 years implant dentistry has made great progress. Especially in the anterior region, esthetics plays a vital role in treatment. Patients expect not only a fully functional restoration, but also an esthetically pleasing and long-lasting solution.
