Dr. med. dent. Stefan P. Bienz graduated with a Master’s in Dental Medicine at the Center of Dental Medicine, University of Zurich, Switzerland in 2011. After a 5-year period as a full-time associate in the private practices of Dr. Andreas Grimm and Dres Ueli Grunder and David Schneider, he completed the 3-year postgraduate training at the Clinic of Reconstructive Dentistry, University of Zurich (2016-2018). He received a Master’s in Oral Implantology from the University of Zurich and is a specialist in reconstructive dentistry. He is currently a full-time Senior Research and Teaching Assistant at the Clinic of Reconstructive Dentistry, University of Zurich. Stefan Bienz’s clinical work encompasses complex and esthetic cases including all aspects of hard and soft tissue regeneration, dental implants and reconstructive dentistry. His scientific focus lies on soft and hard tissue regeneration.

Ziel: Ziel der vorliegenden retrospektiven Fallserie war die Einführung eines minimalinvasiven zweistufigen lappenfreien Verfahrens für die Kronenverlängerung, das die Gingivektomie vermeidet oder minimiert, indem die Reduktion der Knochenhöhe mithilfe einer Tunnelpräparation vorgenommen wird.
Material und Methode: In diese Studie wurden neun Patientinnen und ein Patient (Altersmedian: 46,6 Jahre, Bereich: 26,9 bis 71,6 Jahre) eingeschlossen. Die Indikationen für die Durchführung der Kronenverlängerung waren: ästhetisch zu kurze Kronen (n = 5), Asymmetrie der Gingivahöhen (n = 2) und die Kombination aus diesen Indikationen (n = 3). Alle Behandelten wiesen einen dicken gingivalen Phänotyp auf, und die mittlere Anzahl der in den Eingriff einbezogenen Zähne betrug 3,7 (Bereich: 2 bis 8 Zähne). Drei Teilnehmende erhielten sechs Wochen nach der Kronenverlängerung eine zusätzliche Gingivektomie.
Ergebnisse: Die Ergebnisse erfüllten in ästhetischer und funktioneller Hinsicht die Erwartungen der Behandelten und des Zahnarztes.
Schlussfolgerung: Das minimalinvasive zweistufige Kronenverlängerungsverfahren unter Anwendung einer Tunneltechnik kann auch ohne offenen Lappen und zusätzliche Gingivektomie vorhersagbare ästhetische Ergebnisse liefern. Prospektive klinische Studien sind nötig, um die Technik zu validieren.

Aim: The purpose of the present retrospective case series was to introduce a minimally invasive two-stage flapless crown lengthening procedure where a gingivectomy was avoided or minimized by reducing the bone height through a tunneling technique.
Materials and method: Ten patients (median age 46.6 years, range 26.9 to 71.6 years) were included in the study. The indications for performing a crown lengthening procedure were esthetically short clinical crowns (n = 5), asymmetry of the gingival margin level (n = 2), and both esthetically short clinical crowns and asymmetry of the gingival margin level (n = 3). All the patients presented a thick gingival phenotype, and the mean number of operated teeth per patient was 3.7 (range 2 to 8 teeth). Three patients underwent an additional gingivectomy 6 weeks after the crown lengthening procedure.
Results: The esthetic and functional outcome of the treatments fulfilled the patients’ and dentist’s expectations.
Conclusion: A minimally invasive two-stage crown lengthening procedure applying a tunneling technique has the potential to achieve predictable esthetic outcomes without an open-flap approach and an additional gingivectomy. However, prospective clinical studies are needed to validate this technique.
The aim of the study was to test whether or not, for primary bone augmentation, the use of a xenogenic bone block loaded with rhBMP-2 results in similar bone quantity and quality compared to an autogenous bone block and to evaluate patient morbidity following the surgical procedure with the two treatment modalities. 24 patients requiring implant therapy for the reconstruction of 1 to 4 missing teeth and insufficient bone volume for implant placement were randomly assigned to receive one out of two treatment modalities. Both treatment modalities were successful in regenerating bone to allow for dental implant placement at 4 months. Histologically, a higher amount of mineralised tissue was observed for the control group at 4 months. The use of a second surgical site in the control group tended to a higher patient morbidity compared to the test group, but did not reach statistical significance.
