Focused Clinical Question What is the key clinically controllable preventive measure that may help reduce the incidence of biological complications? Summary Implant complications are common, ineffective care, and delay in diagnosis can lead to expensive time‐consuming surgical and nonsurgical interventions. Careful selection and placement of implant allow development of adequate emergence design of the implant suprastructure. This helps achieve effective plaque control, adequate maintenance at hygiene visits, accurate follow‐up assessments of the peri‐implant tissues addressing the key underlying factor impacting biological complications. This clinically controllable preventative measure may be considered a vital strategy in averting peri‐implant disease. Conclusions Surge in biological complications has led to increased patient dissatisfaction in terms of time, cost, esthetics, and maintenance. One of the factors identified in causing biological complications is the iatrogenic prosthesis‐related factor. Minimizing the impact of this factor is crucial to the overall implant success. Selection and placement of implant following meticulous planning, using careful surgical protocols, allow development of adequate suprastructure design that improves overall patient outcomes by reducing biological complications. Further research is essential to comprehensively assess the impact of these strategies in thwarting development of biological complications.

“…2 Different pontic designs have been described in the literature to promote a natural appearance of the prosthesis, which is essential in the anterior maxilla, where the bone gets quickly remodeled after tooth extraction due to the thin cortical buccal plate present. [3][4][5][6][7] The use of hygienic pontics, convex pontics, esthetic pontics, and other designs are commonly used pontic designs, each with specific indications of use (Table 1). 3,[8][9][10] Regardless of the pontic design, all pontics should ideally be flat or convex, with minimum pressure contact or pressure-free and well-polished to preserve healthy tissues and prevent mucosa inflammation due to plaque accumulation (Figure 1).…”

Objective: Emulating natural dentition with dental implant restorations is challenging, increasing its complexity when a pontic area must be restored. Many different methods have been described to solve this problem. The pontic designs which have been proposed have specific indications and may require additional treatments, including soft tissue augmentation procedures, to increase the possibility of an esthetically pleasing and biologically tolerable outcome. Proper conditioning of the soft tissues during the interim restoration stage and adequate communication with the laboratory are also critical factors to a successful outcome. This article describes the different approaches to restoring pontic sites with different degrees of complexity, their clinical indications, and limitations viewed from a perio-prosthodontic approach. Clinical Considerations: Different clinical scenarios for pontic sites require different approaches. Missing hard and soft tissues can be replaced by surgical or prosthetic means. Understanding the clinical indications and implications of the different pontic designs allows the clinician to make good decisions when planning and treating patients that require replacement of pontic spaces leading to more successful outcomes. Conclusions: Different pontic designs have specific indications as well as biologic and esthetic prognoses. Selection of a good design, proper modifications during the provisionalization stage, and adequate communication with the dental laboratory will lead to higher chances of esthetic and biological success. Clinical Significance: The proper pontic design allows for esthetically pleasing pontic sites which emulate natural emergence from the soft tissues while promoting biological stability.

A pontic is an artificial tooth that substitutes a lost natural tooth, preserves its function, and typically fills the space left by the actual crown. Sanitary/hygienic and modified sanitary/hygienic designs do not contact the alveolar mucosa. On the other hand, ridge lap, modified ridge lap, ovate, modified ovate, and conical are designs that maintain contact with the mucosa. The ideal biological properties to be taken into consideration while designing pontics are periodontal health, access for oral hygiene, no food trapping and occlusal harmony. Accumulation of dental plaque has been implicated in the onset of gingival and periodontal disease as well as caries in the vicinity of the fixed restoration. The connection of the pontic to the supporting crowns must be constructed in such a way as to make a flushable area in the direction of the gingiva, in order to ensure that this area can be cleaned by toothbrushing and flossing but not the large triangular spaces that make it easy for food particles to cling. Modified ridge lap and ovate types, out of all the pontic shapes described below, exhibit convex cleansable faces. Ovate pontics are most effective for use in anterior regions, while the modified ridge lap design can be utilized predominantly in fixed partial denture designs posteriorly. The important etiological factor for gingivitis, periodontitis and peri-implantitis is bacterial colonization which is impacted by the individual's immunologic response and genetic predisposition in addition to dental care practices and pontic design. It is believed that no matter what the material of the pontic is, it must provide a highly polished intaglio surface to help floss slide through and make contact with the full base of the pontic in order to minimize plaque accumulation.
