A 57-year-old woman presented to a private practice with the chief complaint being “I’m self-conscious about the appearance of my teeth. Also, I’ve lost most of my teeth and I cannot eat well because of that”. The clinical and radiographic examination revealed the absence of all teeth except the central incisors and right lateral incisor in the upper. In the lower, partial edentulism, severe bone loss, and multiple periapical infections were diagnosed. Also, the patient’s function and aesthetics were seriously compromised (Fig 1-11).

In the present clinical case, the upper left lateral incisor presented with a vertical fracture. Following a proper clinical and radiographic analysis, the tooth was considered hopeless. The treatment plan consisted of the extraction of the lateral incisor and immediate implant placement. It is well described in the literature that delayed loading, in contrast with immediate or immediate- delayed loading, can lead to predictable results in all clinical situations.
Introduction: Modern dentistry depends on comprehensive diagnostics and careful planning to achieve the desired result and meet the expectations of both the patient and the dentist.
Digital planning and guided surgery based on three-dimensional X-ray data and digitized intraoral recording are of great help. They provide valuable information and allow for accurate backward planning to optimize the implant-prosthetic outcome, making the restoration more predictable in terms of function, aesthetics and biology.
Introduction
The evolution of digital dentistry and the development of a digital workflow has concentrated on digital planning with the use of Cone Beam CT scanning as well as using digital restorative tools to combine DICOM (Digital Imaging Communication in Medicine) and .stl (stereolithography) files to virtually plan, place and restore implants before using this plan to treat patients. The resulting benefits are reduced chair time, high precision and predictable aesthetic results often with immediate fixed provisional restorations available at time of surgery and corresponding high levels of patient satisfaction.
Intra-oral scanning to create digital ‘virtual impressions’ is also becoming more prevalent with the information being stored in the .stl file format. This information can be utilised by appropriate CAD/CAM (computer-aided design and computer aided manufacturing) software to design and manufacture a dental restoration (either by milling or 3D printing).
One area that is sometimes overlooked is the use of digital technology in occlusal analysis and adjustment of the restored dental implant. The following case study examines the occlusal management of a conventionally placed implant.
A 55 year old female patient was referred to our office for a full mouth rehabilitation. Upon clinical examination and a CBCT, we have decided to implant 4 EL C-Tech conical Morse tapered connection implants in the upper jaw for a bar retained over denture and due to financial considerations; was to perform extraction of all remaining lower teeth and immediate post extraction implantation of SD C-Tech mini dental implants. A full muco-periosteal flap was released, teeth were extracted, an alveotomy was performed to achieve an optimal bone platform for the SD mini dental implants and to obtain a bigger vertical dimension for the overdenture!
A 58 years old female patient has come to our clinic for lower jaw rehabilitation. After the clinical examination and OPG, We have decided to extract tooth 33, which is the only one remaining. As thepatient has not accepted a big augmentation procedure, we have decided to implant 4 C-Tech SD mini dental implants for retention and stabilization of the lower denture.

In this case, the patient has a genesis of the two upper lateral incisors.
Having created the space with the help of the orthodontic specialist, we first proceed with a Digital Smile Design and then with the digital planning of the two implants in comparison with the new aesthetics.了解更多

In this case, it is necessary to use all the digital tools available – detection of joint movements, digital smile design and guided surgery, with the aim of having predictability and accuracy. For the future aesthetic part and function, the evaluation took place before the surgery.了解更多

In this case it is shown how it is still possible to work in guided surgery and consequently perform bone grafts where necessary.
The advantage in a difficult case like this is to design the dental implants with a surgical guide, in order to maintain their correct positioning.
Finally, the aesthetic project was evaluated prior to surgery.了解更多
