“…In the last 15 years, with the purpose of minimizing surgical invasiveness and to reduce morbidity and t simplify and shorten treatment, procedures based on breaking down the intimate contact between the implant and the bone through the application of shear stress have been advocated. [62][63][64] An example is localized resection via ultrahigh frequency piezosurgical instruments 65 or laser-assisted devices 66 that have demonstrated utility in removing failing dental implants. Nevertheless, these procedures are time consuming, and their invasiveness is debatable.…”

Inappropriate and unnecessary implant therapy driven by an erroneous belief that dental implants provide enhanced function and esthetics over diseased or failing teeth has led to a growing burden of implant complications across the globe. Specifically, esthetic and biological complications frequently lead to the unfavorable prognosis of dental implants. Often, these cannot be managed predictably to improve the condition or satisfy patients' demands. In such circumstances, implant removal needs to be considered. Currently, minimally invasive methods based on reverse torque engineering are key to preserve peri‐implant soft and hard tissues. Implant replacement is now feasible, as evidenced by the high survival rates of implants placed at previously failed sites. Notwithstanding these data, clinicians should still consider carefully the expendability of an implant and whether its replacement will satisfy the prosthetic, biomechanical, and esthetic demands of the patient. In the scenario where future implant placement is desired, protocols undertaken for soft/hard tissue grafting and implant placement should be based upon defect morphology and soft and hard‐tissue characteristics. Currently, however, a lack of knowledge of the biological events and dimensional changes that arise following implant removal renders decision‐making complex and challenging, and recommendations remain largely based upon empirical speculation. This chapter will review the indications for implant replacement for prosthetic, biomechanical, and esthetic complications, alongside considerations in decision‐making, planning, implementation, and outcomes of implant replacement.

“…2 In certain cases, if there is a problem with the implant (fracture, peri-implantitis, and others) explantation may be necessary. 2,3,6 Bleeding during implant surgery can be a serious setback, but it is especially so when it develops in the floor of the mouth. During the preparation of the surgical bed for the implant, intraosseous or extraosseous perforation of an artery could occur causing bleeding, which may pose a fundamental problem.…”

The placement of dental implants is a safe and predictable procedure when performed by qualified staff. The incidence of complications derived from this type of surgery has increased due to the greater number of patients undergoing dental rehabilitation treatments in recent years. Floor of the mouth hematoma is a rare, but potentially fatal, complication that every oral surgeon should recognize for early diagnosis. As part of the clinical case presented here, two implants were removed and a hemorrhage in the floor of the mouth was found, which required an urgent intervention to control the bleeding. Two independent researchers conducted an electronic search of the available scientific evidence in relation to bleeding of the floor of the mouth in dental implant surgery. The research included references, which were written in English or Spanish, and published up to December 2022. Case reports, case series, systematic reviews, and meta-analysis were part of the inclusion criteria. Sixty-four bibliographic references were identified, and 39 full-text articles were selected. There were 30 cases of floor of the mouth hematoma in relation to implant surgery. In 13 patients the main location was interforaminal, in 5 in the canine area, in 6 in the incisor area, and in 6 in the molar premolar region. All cases were caused by perforation of the cortical bone or surgical manipulation (disruption of the periosteum, perforation of the sublingual mucosa by the stiff suture). The sublingual artery was most frequently involved. The clinical sign observed in all cases was elevation of the floor of the mouth. In 21 of the cases there was airway involvement, so the main treatment was intubation or tracheostomy. Floor of the mouth hematoma may be one complication associated with implant surgery. Given the seriousness of this clinical picture, early detection by the dentist and hospital referral are essential. Warning signs are sudden swelling of the floor of the mouth or submandibular area, accompanied by dysphagia and dyspnea.

“…The employment of less traumatic techniques such as partial resection seems to be required to cause minimal residual hard tissue defects, especially in well-integrated implant cases. 9,16,18 The decision to use partial explantation technique was based primarily on the fact that complete removal of the well-osseointegrated implant portions would cause abovementioned severe complications. However, this implant resection technique is only appropriate when the peri-implant bone is very thin or well-osseointegrated part of the implant is very close to the crucial anatomical landmarks.…”

Dental implant surgery is a highly reliable therapy with widespread use all over the world. However, various accidental symptoms and complications such as peri-implantitis have been reported, and occasionally necessitate implant removal. This alternative technique was performed to minimize the harmful effect of conventional resective explantation procedures. The present case concerns a 55-year-old woman who had two dental implants in the mandibular incisor regions who apparently developed severe marginal peri-implantitis. Presence of lesion was confirmed by two and three-dimensional radiographic images. Explantation was indicated because of the excessive ongoing bone loss around implants. Due to avoid serious complications such as jaw fracture, coronal resection technique (partial explantation) was suggested. After the full thickness flap was elevated, affected part of both implants were resected, and osseointegrated healthy apical parts were left in the basal bone. Wound healing was uneventful at one week follow-up. Proper locater abutments were tightened after 5 months of the partial explantation procedure, and final denture was applied in the oral cavity. The radiologic and clinical examinations showed successful outcome at 12-months follow-up. Minimally resective peri-implantitis therapy may be achieved using this non-traumatic coronal implant resection approach.
