Rotation and Crowding of the Buccally Inclined Tooth represented a favorable Etiological Factor. The patient did not wish to receive Orthodontic Treatment to eliminate this Causal Factor after Completion of Primary Treatment. Treatment was therefore limited to the Surgical Regeneration Attempt. The Interdental Space was larger than 3 mm and the Bone Pocket was a mostly Three-Walled Structure, so the Chances of Success were considered to be good. Exploration was first performed to identify the Course of the Defect Margins. Exact knowledge of the Bone Anatomy in all three Planes is essential to successful Incision Planning. A Tunnel-Shaped Defect delimited by Bone in the Region of Tooth 11 with good chances of Periodontal Regeneration was found. A major Challenge of this Procedure is the need to keep the Defect completely covered with Soft Tissue throughout the Healing Process. Cortellini's Papilla Preservation Technique was used for this Purpose. After Incision and Flap Mobilization, it became evident that the Defect only had two Walls in the Coronal Region and that Bone was lacking in the Buccal Region. According to the current Data on Periodontal Regeneration, the Attachment Gain achieved using an Enamel Matrix Protein (Emdogain®) alone can be just as good as that achieved using Emdogain and Bone Graft Material combined. Still, we elected to use a Combination Technique in the Present Case because it provides better Papillary Support. The Graft Material consisted of Autogenous Bone Chips from the Spina Nasalis, which can easily be harvested by Means of the Piezo Technique After gentle Detoxification, the Root Surface was treated with Emdogain. The Defect was then filled with Autogenous Bone Chips and closed by Microsurgical Suture Techniques. Six months after Surgery, Partial Regeneration of the Papilla can be seen.

Objectives: The aim of this study was to assess the degree of satisfaction of chewing ability among patients treated with fixed partial dentures and/or single crowns supported on dental implants. Methods: The Dental Impact of Daily Living (DIDL) questionnaire was used, which has a dimension for chewing ability, together with a Visual Analog Scale (VAS) for satisfaction values. Interviews were conducted on a total of 183 patients (71 men and 112 women) with a prosthesis in situ for at least one year, placed between 1998 and 2012 at the University of São Paulo. Forty patients had fixed total prostheses and 143 patients had partial dentures and/or single crowns supported on dental implants. To test the association between variables was used Pearson’s chi-squared test. Results: Of those interviewed, 73.2% of patients (52 men) were satisfied with their ability to chew and 85% (34 with total prostheses) reported satisfaction, however there were no statistically significant differences between them and patients treated with partial dentures and/or single crowns and women. Conclusion: The degree of chewing satisfaction of patients treated with total prostheses and men treated with implants was high, mainly because of the stability and comfort of the prosthesis, followed by aesthetics and hygiene. Accurate articulation and aesthetic requirements seem to be not as important for men as they are for women which shows in terms of levels of satisfaction, but the findings are not conclusive.
