The coverage of recessions around teeth is a very successful surgical treatment. The published evidence suggests that periodontal plastic surgeons can very predictably perform these procedures. However, how does reality present? What are the measurement methods and indexes used to support the external evidence? During this lecture, we will look very critically at the evidence we used to support our enthusiasm about the coverage of recession procedures. Second, we will try to answer the raised question in the title of this lecture. Third, the entire thought process will be supported by clinical cases.

Als Folge eines Zahnverlustes kommt es immer zu einer Atrophie des Kieferknochens, welche das spätere Einbringen von dentalen Implantaten erschweren kann. Wenn der Knochenabbau so weit fortgeschritten ist, dass sich keine Implantation mehr durchführen lässt, muss der Knochen operativ aufgebaut werden. Dafür stehen diverse Techniken und Materialien zur Verfügung, die sich durch verschiedene Vor- und Nachteile voneinander unterscheiden. Grundsätzlich ist die horizontale Knochenaugmentation wissenschaftlich gut dokumentiert und kann als zuverlässige Methode angesehen werden, wobei die Technik der gesteuerten Knochenregeneration zurzeit den Goldstandard darstellt. Die vertikale Augmentation des Kieferknochens ist hingegen prognostisch ungünstiger, schlechter dokumentiert und um einiges sensitiver. In dem Beitrag werden die verschiedenen Möglichkeiten des Knochenaufbaus, die heute in der modernen Implantologie zum Einsatz kommen, beschrieben und diskutiert.
Keywords: Horizontale Knochenaugmentation, vertikale Knochenaugmentation, Knochenersatzmaterialien, gesteuerte Knochenregeneration, Distraktionsosteogenese
Immediate implant placement at multirooted molar sites involves a series of site-specific anatomical challenges, including implant bed preparation in the presence of interradicular bone septa. The aim of this article is to present and discuss a novel approach that gives improved guidance during implant bed preparation for immediate implants at multirooted extraction sites in both the mandible and maxilla. Following decoronation of the concerned teeth, osteotomies were performed directly through the teeth's initially retained root complexes. After completion of the drilling protocol, the remaining root aspects were extracted, and treatment was continued in the usual manner. With the osteotomy drills stabilized and guided by the retained root aspects, this approach allows for precise positioning and angulation of the implant bed preparation, thus enabling ideal implant positioning during immediate implant placement at multirooted extraction sites.
In einer Vielzahl klinischer Untersuchungen konnte die essenzielle Bedeutung einer nach Abschluss der aktiven Behandlungsphase regelmäßig durchgeführten parodontalen Nachsorge für die langfristige Funktions- und Gesunderhaltung parodontal geschädigter Zähne eindeutig belegt werden. Das wachsende Verständnis der Existenz eines multifaktoriellen Krankheitsgeschehens, die Assoziation parodontaler Erkrankungen mit anderen chronisch-entzündlichen Allgemeinerkrankungen und auch die stetig steigende Zahl von mit dentalen Implantaten versorgten Patienten verleihen der unterstützenden Parodontitistherapie bzw. der parodontalen Erhaltungstherapie heute zunehmende Bedeutung und Verantwortung und machen sie zu einem zentralen Element präventiv orientierter Zahnmedizin. Der Beitrag möchte in diesem Zusammenhang aktuelle Aspekte der parodontalen und periimplantären Nachsorge beleuchten sowie Anregungen zu deren Umsetzung und Durchführung in der Praxis geben.

Hart- und Weichgewebsdefekte nach Zahnextraktion erschweren die Wiederherstellung einer orofazialen Harmonie. Die sekundäre Rekonstruktion von Gewebsdefekten stellt insbesondere in der ästhetisch kritischen Zone eine klinische Herausforderung dar, weil in diesem Bereich auch kleine Differenzen zwischen der rosa und der weißen Ästhetik optisch wahrgenommen werden können. Um im Bereich der rosa Ästhetik klinisch nahezu perfekte Ergebnisse erreichen zu können, muss ein kompletter Gewebserhalt angestrebt werden. Mit einer neuen Technik (Socket-Shield-Technik) scheint es möglich zu sein, durch Erhalt eines Anteils der bukkalen Zahnwurzel die Dimensionsveränderungen nach Zahnextraktion zu vermeiden.

Purpose: The purpose of this clinical trial was to evaluate whether the crestal bone height around dental implants could be influenced by the use of a platform-switching protocol.
Materials and Methods: All implants placed in the year 2006 in healed bone without any need for ridge augmentation were included in this study. The following groups were created: (1) wide-diameter implants were placed subcrestally and regular-diameter cover screws were connected; (2) regular-diameter implants were placed at the crest and regular-diameter cover screws were connected. Standardized radiographs were obtained after insertion of the definitive prosthesis and after 1 year. Calibrated measurements were conducted initiating from the mesial and distal bone peaks to the implant-abutment junction. The average value of the mean medial and mean distal values was calculated and analyzed with an unpaired two-tailed t test. P values < .05 were regarded as statistically significant.
Results: In all, 89 dental implants in 36 patients were evaluated. The implants with a platform-switched configuration (n = 75) exhibited statistically significantly less bone loss at time of insertion of the definitive prosthesis (0.30 ± 0.07 mm versus 0.68 ± 0.17 mm; P < .05) and at 1 year (0.39 ± 0.07 mm versus 1.00 ± 0.22 mm, P < .01) when compared to the nonplatform-switched implants (n = 14).
Conclusion: Platform-switched implants seem to limit crestal bone remodeling.

The esthetic outcome of implant-supported restorations has become increasingly important, especially for single-tooth implants in the esthetic zone. Because of the morphologic alterations that occur following tooth extraction, augmentation procedures are often necessary before, during, or after implantation to achieve an esthetically pleasing result. This article describes a modified technique for augmenting the soft tissue during stage-two implant surgery. The technique uses a modified roll flap, in combination with a tunneling approach to the adjacent teeth and a coronally positioned palatal sliding flap, to achieve sufficient horizontal dimensions and a scarless and harmonious architecture of the peri-implant soft tissue.
To enable uneventful and accelerated healing processes to occur, common techniques in plastic periodontal and implant surgery focus on stable postoperative flap positions. Flap stability is, in particular, positively influenced by an adequate suturing technique, which therefore represents one important factor with regard to the predictability of successful treatment outcomes. The following article illustrates the use of a modified suturing technique, which aims to improve wound adaptation and soft tissue stabilization after surgical treatment with tunneling flap preparation techniques. Anchored at the incisal contact points of the affected teeth, the suture is crossed through the buccal as well as through the palatal aspect. In this manner, the suture maintains the surgically established coronal displacement of the buccal flap and provides a stable and intimate contact to the underlying tissues.
Um einen möglichst komplikationsarmen und zügigen Heilungsverlauf zu ermöglichen, wird in der plastischen Parodontalund Implantatchirurgie sehr auf stabile Wundverhältnisse respektive eine stabile postoperative Lappenposition geachtet. Dabei wird die postoperative Lappenstabilität maßgeblich durch die Anwendung einer adäquaten Nahttechnik positiv beeinflusst, weshalb diese einen Schlüsselfaktor zur Erzielung eines vorhersagbar erfolgreichen Behandlungsresultates darstellt. Im nachfolgenden Artikel wird die Durchführung einer modifizierten Nahttechnik gezeigt, deren Ziel eine verbesserte Wundadaptation und Weichgewebsstabilisierung nach chirurgischer Behandlung mit tunnellierenden Lappenpräparationstechniken ist. Hierbei wird die Naht an den inzisalen Kontaktpunkten der betreffenden Zähne verankert und sowohl von bukkal als auch von palatinal durch den interdentalen Weichgewebskomplex geführt. Auf diese Weise sichert die Naht die intraoperativ etablierte koronale Verschiebung des bukkalen Lappens und sorgt gleichermaßen für dessen stabilen und innigen Kontakt zu den darunterliegenden Geweben.
Purpose: This dog study sought to evaluate guided bone regeneration (GBR) in peri-implant defects following implantation of b-tricalcium phosphate (b-TCP) with and without osteoinductive recombinant human growth/differentiation factor-5 (rhGDF-5).
Materials and Methods: In five beagle dogs, all mandibular premolars and the first molar were extracted. After 2 months, six buccolingual critical-size defects were created, and an implant was inserted into the center of each defect. One defect was filled with b-TCP coated with rhGDF-5 (600 µg/g b-TCP) and covered with a titanium-reinforced e-PTFE membrane (GDF group). A second defect received the same treatment, but pure uncoated b-TCP was used (TCP group). A third defect was filled with b-TCP mixed with autograft and not protected with a membrane (control group). The remaining three defects were filled with other biomaterials. After 2 months, total new bone area, regenerated bone height, and residual amount of b-TCP were determined histomorphometrically.
Results: All implants osseointegrated. One membrane in each group became exposed. Mean new bone area for GDF, TCP, and control sites was 43.9 ± 18.7 mm2, 32.3 ± 16.1 mm2, and 13.1 ± 4.0 mm2, respectively, with a significant difference between GDF and control groups. Mean regenerated bone height was 103.8 ± 29.7%, 75.4 ± 36.6%, and 67.2 ± 19.1% for the GDF, TCP, and control groups, respectively. Mean residual matrix volumes were 25.9 ± 13.6%, 30.0 ± 13.0%, and 13.4 ± 6.5%, respectively. Membrane protection of peri-implant defects filled with b-TCP resulted in a stronger effect on bone regeneration, although this was not statistically significant. The most pronounced regenerative results were achieved in rhGDF-5/b-TCP filled membrane-protected defects.
Conclusion: Delivery of rhGDF-5 on b-TCP might have the potential to enhance the results of GBR in peri-implant defects.
