Minimizing alveolar bone loss
Fig. 1: Gentle tapping with a mallet on the scalpel handle with #15c blade is used to separate the coronal PDL fibers.
Fig 2: The periotome is engaged into the created PDL space to luxate the root.
Fig. 3: Sectioning of a single root for an atraumatic extraction
Fig. 4: Vertical sectioning the mandibular first molar along the buccal groove that anatomically coincides with the furcation.
Fig. 5: The elevator is employed to create a wedge effect between the sectioned tooth structure to facilitate luxation between the separated tooth fragments.
Fig. 6: A circum-radicular piezo surgery is performed in a circumferential direction around an anterior tooth, with the exception of the facial side so as to preserve the facial alveolar bone plate and maintain esthetics.

Fig. 8a: Reduction of teeth # 9 and 10. #8 and 11 will act as abutments for the provisional bridge
Fig. 8b: Bleeding epithelial edges that will promote creeping substitution on roots #9 and 10.
Fig. 8c: “Relieved” pontics #9 and 10 allow for creeping substitution and gingival coverage
Fig. 8d: Completed healing. Marginal correction of gingiva obtained under the pontics
Fig. 8e: Gingival growth over roots of #9 and 10
