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.
by Doctor Henriette Lerner, HL-DENTCLINIC DR. STOM. MEDIC.
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.

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.

A 67-year-old female patient presented to a private dental office with pain on the first quadrant. The clinical and radiographic examination revealed extensive caries and a history of root canal therapy failure on teeth #1.3 and 1.5. Also, absence of teeth #1.4 and #1.6 (Fig. 2-4).

| Chief Complaint: Missing an anterior tooth in the upper left region, the patient seeks fixed restoration. | |
| Consideration(s): | |
The upper left tooth 2 is missing. It will undergo restoration using a C-Tech implant (Model: EL-3511). A subsequent application of an oxidized zirconia porcelain crown is planned for the final restoration.
The width of the alveolar bone in the region of the upper left tooth 2 measures 5.7mm, and the height is 14.02mm, which is deemed to be ideal. The proposed approach is to implant a C-Tech implant (Model: EL-3511) in this area. The second stage of the surgery is scheduled for three months later.
1、Perform standard disinfection and drape the area with cloths.
2、Administer local anesthesia to the upper left tooth 2, ensuring minimal discomfort. Create a horizontal incision along the crest of the alveolar ridge, extending from the near to far and central aspects. Carefully reflect the gingiva to expose the underlying bone surface.
3、Precisely position the C-Tech implant (Model: EL-3511) in the location of the upper left tooth 2. Gradually prepare a tapered borehole measuring 3.0x13mm to accommodate the implant, ensuring a precise fit. The implant is integrated with the healing abutment (Model: EL-5506HT) and anchored with a torque of 10N, achieving a marginal bone height of M3D4 B1.5L2. Securely suture the area.
4、After 4 months, take an impression and replace the restorative abutment with Model: EL-4504F. Permanently fix it with adhesive fixation, and apply an oxidized zirconia porcelain crown for long-lasting restoration.

The patient is a 52-year-old male with no medical history.
Chronic periodontitis is stabilized.
Former smoker who quit following periodontal treatment.
Teeth 26, 16 and 17 were extracted. Considering that the available bone height was low, a bilateral sinus lift was performed by lateral approach.
Watch Dr Henriette Lerner explaining all the features of a successful and qualitative implant.
I saw you have breathing plant systems in the pipeline and you learn a lot of systems, and probably you already have in your mind some main features that the implants need to have.
In order to make your treatment easier and more predictable in your procedures.
You probably already know that an implant has to have a high bone implant contact surface and the designs of the implants are all made in a way that increases this surface, because this is giving you a long-term stability of the surface of the osteointegration.

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.

Patient is a 56 years old male without a previous medical history. Tooth # 36 has been missing for several year.
Despite a satisfactory bone height on the panoramic, the CBCT reveals a thin bone at the level of the crest which does not allow the available height to be exploited.
In order to obtain an ideal prosthetic axis and to use the available bone to the maximum, the surgery is performed using a surgical guide, design on 3Shape Implant Studio, a classic dentition supported guide, 3D printed on a Phrozen Shuffle printer.

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.

Introduction
The use of Cone Beam Computerised Tomography (CBCT) scanning is becoming more commonplace in today’s implant dentistry. These scans combined with increasingly sophisticated software technology has led to greater accuracy in digital planning and guided surgery and is gradually being adopted across general practice. Furthermore, the restorative planning can be digitised and combined with the CBCT data in appropriate planning software.
In conjunction with these technology advances, dental implant design has evolved to incorporate the latest concepts of biomechanical design, which include sophisticated thread profiling, platform switching and a Morse locking taper on the implant/abutment interface.
The following case details brings these advances in implants and digital technologies together.

Introduction
There has been a considerable evolution in implant dentistry over recent years that has seen the design of dental implants adopt sophisticated thread profiles which leads to a better primary stability. Simultaneously these new geometries aid cortical bone maintenance through to platform-switching capabilities again designed to minimise bone loss. When combined with improved implant-prosthetic connections such as a Morse-locking conical connection it contributes to a good long-term prognosis and an aesthetic outcome.
Concurrent with this evolution in implant design have been substantial advances in digital technologies across the field of dentistry. These digital advances include Cone-beam CT scanning combined with appropriate 3D planning software, navigated surgery technology, 3D intra-oral scanning to create a ‘virtual impression’ and 3D printing technologies. These digital technologies can minimise the number of appointments found in a conventional treatment protocol as well as enabling greater accuracy and will be considered in this case study.
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!
