Abstract Background: Sagittal root position (SRP) and thickness of buccal plate were of clinical guiding significance in implant treatment planning. The study was to classify the SRP and angulations of the maxillary and mandibular premolar to each osseous housing, and to measure the thickness of buccal plate by cone beam computed tomography (CBCT) in order to estimate the distributions and provide clinical decision support. Methods: CBCT images was reviewed on 150 patients who fulfilled the inclusion criteria. The sagittal root position and angulations of the maxillary and mandibular premolars to their respective osseous housing were evaluated and classified using CBCT images. The thickness of buccal plate at 1 mm, 3 mm, 5 mm apical to the alveolar crest was also measured. Results: The frequency distribution of SRP types indicated that, 41.67%, 51.83%, 3.67%, and 2.83% of maxillary premolars; 84.33%, 15%, 0%, and 0.67% of mandibular premolars were classified as type B, M, L, and N. The frequency distribution of angulation classifications indicated that, 20.83%, 46%, 32.17%, and 1% of maxillary premolars; 2%, 5.33%, 36.67%, and 56% of mandibular premolars were classified as class 1, 2, 3, and 4. The buccal bone thickness in most locations of premolar sites was less than 1 mm. Conclusions: The classification of clinical relevance of SRP and angulation of the premolar root to osseous housing would help for treatment planning and improving interdisciplinary communication of immediate implant placement (IIP) in the premolar region.

Despite numerous advantages over multislice computed tomography (MSCT), including a lower radiation dose to the patient, shorter acquisition times, affordable cost, and sometimes greater detail with isotropic voxels used in reconstruction, allowing precise measurements, cone beam computed tomography (CBCT) is still controversial regarding bone quality evaluation. This paper presents a brief review of the literature on accuracy and reliability of bone quality assessment with CBCT and a case report with step-by-step predictable treatment planning in esthetic zone, based on CBCT scans which enabled the clinician to evaluate, depending on bone volume and quality, whether immediate restoration with CAD-CAM manufactured temporary crown and flapless surgery may be a treatment option.

Gingival Phenotype

Background: Immediate implant placement and provisionalization (IIPP) is considered as a high-risk treatment for aesthetic failure and generally only recommended in case of post-extraction intact sockets and a thick phenotype gingiva. During a prospective clinical cohort study on one-hundred consecutive patients, using this strict flapless immediate implant placement and provisionalization (FIIPP) protocol, we found high and stable aesthetic outcomes (WES/PES = 8.2/12.1) in both intact – and defect sockets, and both thin- as thick gingival phenotype. By means of one case report (Case 1), the total FIIPP treatment is illustrated. Results of two other cases, show that comparable high aesthetic outcomes can be reached in cases with a thin phenotype gingiva or buccal bone defect using the same protocol. Case Presentation: In a 24-year-old male with good general and oral health, root fracture of tooth 21 was diagnosed and FIIPP was indicated. Direct post-extraction, an implant was placed in a palatal position of an intact socket by a flapless approach. A minimum space of 2 mm in front of the implant was created and filled with a bone-substitute prior to implant placement. Subsequently, the implant was restored by use of a titanium abutment and a composite temporary crown. Three months later, the temporary crown was replaced by a customized zirconium abutment and ceramic crown resulting in a high aesthetic outcome. A comparable aesthetic outcome using this protocol can be reached in cases with a thin phenotype gingiva and/or a buccal bone defect (Case 2). Conclusion: Using described surgical FIIPP protocol, high aesthetic outcomes are reached in only 4 visits and within a treatment period of 4 months. A thin phenotype gingiva, or a pre-operative buccal bone defect, does not seem to affect the aesthetic outcome using this treatment method.
