Despite the reduced amount of available bone, it was possible to reach a 35n/cm torque value for the implant stability and this allowed the placement of an immediate prosthesis (Fig. The SAC Assessment tool (based on ITI SAC Classification) can be successfully used for this matter. Clinical cases like this one are also supported by Straumann® Smile in a Box™ - a flexible treatment planning and manufacturing service. 2018 Aug 15. Fig. 55-56). Prosthetic Solutions. It’s important to understand that while zirconia dental implants are VERY strong, they have less flexural give than a metal alloy implant. Finally, a risk profile will be created according to the provided data. It drives the choice of the drills that must be strictly followed in order to perfectly stick to the implant planned positioning. Implant or Abutment Level Abutment Level (12) Implant Level (5) These included an immediate implant placement into a fresh extraction socket and immediate implant loading to replace a hopeless upper deciduous canine. Nowadays, patients are more conscious of their health and esthetics than ever before. As described in the instructions for use, the drilling procedure was carried out until the stop, located on the drill itself. (, 3.    Processing of Dicom (CBCT exam) and STL (optical impression and digital wax-up) data in coDiagnostiX® planning software in order to carefully plan the implant placement and design surgical guide. prosthetic restorations for Straumann® Bone Level Implants. Their well-proven zirconia material also helps surgeons and prosthodontists looking for less plaque attachment and enhanced soft tissue healing from the day of surgery. �tNZ2�0&2�c1l�,`��K��7�˜p�����`GG[ZFG�`R� Q�����@?�#H,�2d��F�Ɍ�� &��� . full zirconia implants available in two parts. Fig. 0000016460 00000 n These included an immediate implant placement into a fresh extraction socket and immediate implant loading to replace a hopeless upper deciduous canine. 20: In accordance with the STL file produced in coDiagnostiX®, the surgical guide was printed. II. Slight modifications were made, and a bite registration was taken. systemic conditions, local factors, etc.) 39). The Straumann PURE Ceramic Implant is a dental implant made out of yttrium-stabilized zirconium dioxide (Y-TZP). Fig. Study models were sent to Burbank Dental Lab. 56: Occlusal view of the crown on the model: note the exact positioning of the screw hole due to the precise implant placement with computer-guided surgery. 18 -19). 38: The dedicated BLX transfer piece drove the implant in the correct position. Fig. 0000007283 00000 n 57-58). The use of a computer-guided approach will assure the precision needed in a case with such a limited vertical bone availability for the implant placement. 5-7). 33: Use of pilot drill (2.2 mm diameter). 0000007800 00000 n Then, the modeling of the zirconia crown to be veneered after milling on the vestibular side with ceramic was performed. Following guide placement and verification of the fit, the dedicated set of surgical instruments were ready to use (Fig. 43). The implant was virtually inserted into the model and the Variobase® RB with a diameter of 3,8mm and a gingival height of 1,5mm was placed on top of it (, Then, the modeling of the zirconia crown to be veneered after milling on the vestibular side with ceramic was performed. At this point we could say that we cover all our patient’s needs and expectations and we can appreciate a big improvement in comparison to the baseline situation (Fig. 9: Cone Beam Computed Tomography (CBCT) exam shows the presence of the impacted canine. Mandibular full-arch restoration with Straumann implant-supported metal mesostructures and zirconia-based prosthesis: a case report. Both final restorations were received in a printed resin model, that allowed us to visualize the final result (, For the cementation of ceramic veeners, it is fundamental to have an absolutely dry area. In the extraoral examination, the facial evaluation showed a symmetrical and proportional face. �Bc4Ş 61-62). �b�} ؄.zC��������(C �L� ���dEA��P+�Χ�{��U����@� �16�@�Cz6$$�-�����ȝi��� 65-66) and finally, she was involved in a maintenance program for follow-up visits once per year. Fig. 0000002055 00000 n 53-54). 50a and b: the STL files related to optical impression were imported in Dental Wings lab modeling software. 63). The new smile was harmoniously integrated in the patient’s face (Fig. Fig. 44) and post-op X-rays images were taken in order to ensure the precision of the implant and the provisional restoration (Fig. The protocol for this patient considered the placement of a Straumann® BLX® ø4.5mm and 8 mm length in a soft bone, and only 3 drills were required (Fig. 66: New smile is harmoniously integrated in the patient’s face. The analysis of the smile presented the midline sagittal plane coincident with the medium line of smile, and the exposure of the upper incisors and canines was 90% (Fig. The Straumann® Dental Implant System was designed on the basis of simplicity and freedom of choice. The rationale of our treatment plan relied on the following facts: Regarding the improvement of the smile and considering the patient’s request, the implant treatment of the left canine was planned to be followed by a modification of the shape of the right lateral incisor with a ceramic veneer. As we were seeking for the most conservative and efficient approach, our preferable option was to place a post-extractive implant and provisional restoration in the site 23 leaving the permanent impacted canine in its position, as this allows a shorter treatment time and a better patient morbidity and esthetics (, Within the treatment planning, it is also fundamental to identify and consider the degree of complexity and potential risk involved in the case. 44: After the refinements, occlusion was checked in the patient’s mouth. Fig. High-performance Zirconia 13 Institut Straumann AG, Straumann® PURE Ceramic Implants A 100 % proof test ensures reliable implant strength. Following the milling of the zirconia crown and the ceramic veenering, the crown was cemented on the Variobase® using a composite cement (Fig. 13: Following the SAC Classification, this specific case is considered as “complex”. Fig. 2: Frontal view of the patient’s smile. The implant was virtually inserted into the model and the Variobase® was seated on top of it. Abutment Level (21) Implant Level (9) Implants and Abutments. Fig. 49). 32: After the guide placement, the milling cutter bur was used with the purpose of creating a flat surface for the precise work of the further drills. Straumann® Mini Implants. Dental implants and Straumann move hand in hand. 0000013812 00000 n 22: Lateral view of the printed model: Note that the shape of the provisional canine crown is now in line with the adjacent teeth.
