Procedure Case description: -Class II furcation defect at teeth 46 and 47 and gingival recessions at teeth 43 and 44 - Root planing using PerioSet - Incision technique - Cleaning furcation defect at tooth 46 - Pref Gel application, rinsing and Emdogain application - Insertion of Bio-Oss into the furcation space with an amalgam plugger after hydration - Condensation of the bone replacement material and application of an absorbable membrane (Bio-Gide) - Atraumatic suture closure using 6/0 Seralene Contents: This video demonstration shows the simultaneous treatment of recessions at teeth 43 and 44 and of class II furcation defects at teeth 46 and 47. After a brief case description, root planning is done using PerioSet. Next, an incision is made and the furcation defects are very carefully cleaned using hand instruments and ultrasonic scalers (Soniflex). The cleaned root surfaces and furcation defects are conditioned with Pref Gel (Straumann) for two minutes. The objective of conditioning is to remove the smear layer, to open the dentine tubules, and to enable surface demineralization. Moreover, this measure serves to optimize the contact between Emdogain and the root surface. After two minutes, the EDTA suspension is removed using physiological saline solution or water spray. Immediately afterwards, Emdogain is applied to the blood and saliva-free root surface. This procedure was also used to treat the furcation defect at tooth 47. Regenerative treatment of tooth 46 was performed since that tooth had a very extensive furcation defect. The defect was filled with Bio-Oss, which was applied using an amalgam plugger. Absorbable Bio-Gide was used for coverage of the furcation entrance. Finally, the wound was closed using loop sutures and single interrupted sutures.

Procedure: Incisal Edge Restoration and Repair - Description of defect and problems related to its repair - Airborne particle abrasion and adhesive pretreatment - Biomimetic layering with enamel and dentine mass - Refining, production of halo effect, polishing Contents: The cervical fracture surface lies in the composite region of an underlying Black III cavity. In the past, this completely intact filling probably would have also been removed because of the fracture. Today, it is possible to treat the problem as a repair and leave the neighboring composite restoration in place while maintaining strict adherence to minimally invasive procedure. Even with the help of magnifying glasses, complete removal of the filling probably would have led to enlargement of the defect since the filling had been in place for 10 years. We therefore opted to pretreat the target area near the composite by means of intraoral airborne particle abrasion (Micro-Etcher system using 27 µm Al2O3 powder) before applying phosphoric acid to the enamel and dentine for conventional conditioning. This was followed by the bonding procedure, comprising the application of dentine adhesive to enamel, dentine and the aged composite material. This technique has already been described in the recent literature (Frankenberger et al. Am J Dentistry, 2003). The reconstruction was performed using an enamel and dental mass of esthetic composite material with the help of a silicone key positioned palatinally. This makes it possible to achieve a biomimetic and natural restoration, including a halo effect. Last photograph: Next recall.

Procedure: - Introduction: History -Taking, Examination, Diagnosis, Etiology, Prognosis for Individual Teeth - Four - Phase Treatment Sequence - Modified Papilla Preservation Technique(MPPT) - Simplified Papilla Preservation Technique (SPPT) - Findings 6 months after Surgery Synopsis The Modified and Simplified Papilla Preservation Techniques for conservation of interproximal papillary tissue were designed to provide access to deep and narrow bony defects to enable regenerative periodontal treatment. The Modified Papilla Preservation Technique (MPPT) was designed to ensure tension-free primary closure via barrier membranes in patients with small interdental spaces. The Simplified Papilla Preservation Technique(SPPT) is used to gain access to narrow interdental spaces ( < 2mm) and to deep defects in the lateral tooth region. Apart from preserving primary wound closure in the interdental space, the two techniques also serve to keep the membrane from collapsing into the bony defect. Both MPPT and SPPT employ special suture techniques to ensure tension-free primary closure of the interdental space. This video clip also serves to demonstrate that the two techniques of interproximal tissue preservation can also be used for periodontal interventions without regenerative measures.
