For immediate implants in the anterior region, the socket-shield technique has received much attention in recent years. However, this technique is technically sensitive and root preparation is difficult. It is also difficult to obtain the ideal three-dimensional position for implant placement in the anterior region. This paper reports a clinical case in which socket-shield preparation and implant cavity preparation were performed with the aid of a dual guide in implant surgery. The dual guide surgical preparation technique was used to reduce the difficulty of socket-shield preparation and to achieve restoration-orientated implant placement with satisfactory clinical results.

Orthodontic space closure following tooth extraction is often hindered by alveolar bone deficiency. This study investigates the therapeutic use of nuclear factor-kappa B (NF-κB) decoy oligodeoxynucleotides loaded with polylactic-co-glycolic acid nanospheres (PLGA-NfDs) to mitigate alveolar bone loss during orthodontic tooth movement (OTM) following the bilateral extraction of maxillary first molars in a controlled experiment involving forty rats of OTM model with ethics approved. The decreased tendency of the OTM distance and inclination angle with increased bone volume and improved trabecular bone structure indicated minimized alveolar bone destruction. Reverse transcription-quantitative polymerase chain reaction and histomorphometric analysis demonstrated the suppression of inflammation and bone resorption by downregulating the expression of tartrate-resistant acid phosphatase, tumor necrosis factor-α, interleukin-1β, cathepsin K, NF-κB p65, and receptor activator of NF-κB ligand while provoking periodontal regeneration by upregulating the expression of alkaline phosphatase, transforming growth factor-β1, osteopontin, and fibroblast growth factor-2. Importantly, relative gene expression over the maxillary second molar compression side in proximity to the alveolus highlighted the pharmacological effect of intra-socket PLGA-NfD administration, as evidenced by elevated osteocalcin expression, indicative of enhanced osteocytogenesis. These findings emphasize that locally administered PLGA-NfD serves as an effective inflammatory suppressor and yields periodontal regenerative responses following tooth extraction.

The facial musculature is part of a biocybernetic feedback system within the stomatognathic system, the continuity of which is disturbed by clefts of the lip, jaw, and palate (cheilognathopalatoschisis). This results in topographic, fine-structural and functional alterations of the facial musculature. In two heads with unilateral clefts and two heads with bilateral clefts, the facial musculature was dissected and the M. orbicularis oris macroscopically and topographically examined. We found changes in the attachment of the M. orbicularis oris. The modiolus, which is coresponsible for the proper topographic relation of the M. obicularis oris to the other facial muscles, was unchanged. Further, we examined the vascular system of the muscle, which likewise adapts to the altered situation. Lip/jaw/palatal clefts result in anatomically functional and fine-structural alterations of the M. orbicularis oris, while the rest of the facial musculature remains unchanged.

Tooth extraction in the esthetic area is usually accompanied by hard- and soft-tissue changes. The socket-shield technique is an effective method for preventing these undesirable changes. However, difficulty in preparing the socket shield and controlling the implant position might increase the complication rate along with the time needed for the surgery, limiting its widespread use. This clinical report demonstrates a digital protocol for accurate and rapid socket-shield preparation and implant placement with surgical guides.

The present study evaluated the quantitative effects of platelet-rich fibrin (PRF) for the repair of extraction socket in Sprague Dawley (SD) rat model by assessing several key clinical parameters. Seventy two male SD rats were subjected to surgical extraction of the maxillary right incisor. Rats were randomly divided into four groups with eighteen rats in each group based on the treatment received: extraction socket without treatment of PRF was taken as control (group I). Extraction socket implanted with 0.1, 0.2, and 0.4 mL of PRF was taken as study groups (groups II, III, and IV). The obtained results demonstrated that, low dose of PRF efficiently enhanced the natural healing cascade. Whereas, high dose interfered with native tissue contribution and altered the natural healing process. The beneficial effects of quantity-based application of PRF may raise the possibility of a new approach as complementary therapy besides conventional treatment.

OBJECTIVE
Tooth autotransplantation (AT) is a viable option for the replacement of unrestorable or missing teeth. Recently, the use of a 3D replica of a donor tooth constructed from CBCT scans was described. The model is made to assess the recipient site's size and minimize the required extraoral time of the donor tooth after extraction. The aim of the paper was to describe a new technique for AT using the 3D replica as a socket preparation tool.
CASE REPORT
A 13-year-old boy who presented with hypodontia was referred for consultation and treatment. The treatment plan included combined orthodontic treatment and AT of the mandibular left second premolar into the site of the congenitally missing maxillary right canine. A titanium 3D model of the donor tooth was printed by a direct metal laser 3D printer utilizing the model from the CBCT scan. An intrasulcular flap was elevated, and the edentulous maxillary ridge was prepared using implant trephine burs with increasing diameters. A surgical mallet was utilized to apply vertical forces to the 3D-printed model, which was inserted into the prepared socket to allow a perfect fit for the donor tooth. After atraumatic extraction of the mandibular left second premolar, the donor tooth was inserted into the ready socket and splinted. Follow-up examinations at 1, 3, and 6 months, and 1 year after surgery demonstrated a successful outcome.
CONCLUSION
The titanium replica was successfully used for precise preparation of the recipient site, minimizing the extraoral time of the procedure to 4 minutes, and thereby improving the expected outcome. (Quintessence Int 2023;54:142-148; doi: 10.3290/j.qi.b3649031).

Much has been published on the socket-shield technique since its introduction to implant dentistry in 2010. The literature reports the technique to be a viable treatment option. Investigations should hence focus on improving the treatment, identifying pitfalls, and better educating clinicians. The technique has been advised as contraindicated at tooth roots with periodontal defects. The present case report aims to illustrate the additional risk and why intrabony periodontal defects may be a contraindication to this already challenging treatment.

Clinical Trial Randomized Controlled Trial
AIMS AND METHODS
Twelve UCLP and eleven BCLP patients who had been treated according to the Hanover treatment protocol were evaluated by means of cephalometric analysis and cast measurements. The aim of this investigation was to demonstrate changes in the vertical plane and in incisor position in the course of craniofacial growth compared to age-matched non-cleft controls. Lateral cephalograms and casts were analyzed for each cleft patient at age 10 and 15 and compared with corresponding data of a non-cleft control group (n = 20).
RESULTS
A vertical growth impairment of the maxilla was registered in patients with cleft lip, alveolus and palate. The maxilla of the cleft patients showed a significant clockwise rotation while the inclination of the mandible remained virtually unchanged. Both upper and lower incisors, which were significantly retruded at the beginning of the late mixed dentition, could be protruded in the course of craniofacial growth, development of the dentition and treatment, but remained retruded in comparison with the non-cleft controls. The posterior midfacial height was highly significantly shorter in both UCLP and BCLP patients at both evaluation timepoints, whereas the anterior lower jaw height was greater than in the control group
