Abstract
One of the most key areas of dentistry is dental implant surgery. The use of digital equipment and software in dentistry has developed considerably in recent years compared to other fields of medicine. Since examining the advantages and disadvantages of each approach, along with case studies, can help physicians make informed decisions, this review study aims to raise the awareness of dentists to make easier decisions about using guided or free-hand surgery. When planning for a dental implant, one of the most challenging questions that doctors face is which method to use (guided surgery or free-hand). Choosing the right method, such as other clinical considerations, will depend on the individual circumstances of each patient and the preference of the treating physician. Free-hand surgery is a cost-effective method in which the flap is reflected, and, according to the doctor's diagnostic information, an implant is placed, which in many cases is a useful method. Guided surgery has the highest level of accuracy and control, in which osteotomy is designed and printed through a digital surgery guide, and depending on the complexity of the case and the patient's anatomy, it has a higher level of value than free surgery. The surgical guide helps the surgeon make the implant surgery more accurate, safer, simpler, at a lower cost, and in less time. In fact, there are patterns that convey information about the position of the tooth to the dentist before the implant is placed.
Highlights
Dental implants are performed when a person has lost a tooth for any reason, and the implant is used to fill in the gaps [1]
One of the key factors that make implants known as a reliable option is successful osseointegration, which requires a method that achieves minimized surgical complications such as nerve damage, perforation, and cortical plate perforation to achieve this goal and achieve the desired result [3]. e most common clinicalpathological findings associated with dental implants are hard tissue defects [4], such as defects at implant sites encompass intra-alveolar [5], dehiscence, fenestration, horizontal ridge [6], and vertical ridge defects and soft-tissue defects include volume and quality deficiencies with a lack of keratinized tissue [7], which can lead to marginal bone loss, soft-tissue inflammation, and soft-tissue stagnation [8,9,10]
Successful use of guided implant surgery has been reported in people who have completely lost their teeth for any reason, along with the concomitant delivery of a prefabricated prosthesis for immediate replacement of missing teeth [82]
Summary
Dental implants are performed when a person has lost a tooth for any reason, and the implant is used to fill in the gaps [1]. It is important to understand that surgeons usually tend to place the implants in the largest volume of bone left, but in most cases, this shape of the implant has caused the buccal or lingual position of the implant to be too much, and it provides problems for prosthodontists and laboratory technicians in preparing prostheses as efficiently and beautifully as possible [13] Such problems remain hidden from the surgeon and patient until the implant is cast, and the prosthodontist uses very expensive equipment and unusual prostheses to treat the patient, which, it leads to the preparation of prostheses, in the end, despite all the efforts of the prosthetic staff, is inefficient and ugly for the patient and sometimes causes legal issues which, pleases no one [14]. The use of new technologies and modern software provides the possibility of three-dimensional examination of the location of implants, making the diagnosis and treatment of patients more reliable [15]
