INTRODUCTION: In the end of 90's the adoption of mini-implants as Anchorage allowed a paradigm change influencing even the way of thinking orthodontic mechanics. The overlapping of the specialties of Orthodontics and Implantology started with orthodontic preparations for prosthetic implants insertion, aroused with the use of palatal implants and late with the introduction of mini-implants. The improvement of mini-implants insertion technique with the appearing of self-drilling screws has allowed orthodontists to plan and to place this precious Anchorage piece. Taking into account the versatility of positioning of these screws it was developed a concept that allows the construction of force action lines aiming at optimize the planning and predictability of orthodontic motion. OBJECTIVE: To present some clinical results treatments conduct using Centrex System of orthodontic treatment, approximating the force line action of resistance center of units to be moved. The traced way to its development, previously treated in this journal, will be detailed for better understanding of its functioning.

Implant Anchorage

Mini screws represent a new treatment modality in orthodontic biomechanics. They provide absolute anchorage, no secondary movements and reduced orthodontic treatment time. Futhermore, the surgical procedure for mini implants placement is quite simple and this type of treatment requires no patient compliance. We selected a clinical case in order to emphasize one of the most important indications of the mini implants: retrusion of the upper incisors for a incresed overjet case in a young patient. Two mini implants were placed in order to obtain the correction of the overjet and the retrusion of the anterior teeth. The retrusion was obtained in a reduced period of time using retraction devices on crimpable hooks.

ABSTRACT Introduction: Orthodontic treatment in patients with traumatized teeth is a condition that needs good planning in order to achieve satisfactory results. Objective: To discuss approaches to orthodontic treatment of malocclusions associated with trauma followed by avulsion of anterior teeth, reimplanted after a short period of time. Case report: The treatment started with the distalization of upper posterior teeth, with the aid of mini-implants and sliding jigs, followed by the inclusion of anterior teeth in the arch, followed by intrusion of these teeth. Results: With the treatment, improved mobility of the anterior teeth was achieved, with better insertion into bone tissue. The most important factor for satisfactory treatment and a good prognosis for avulsion is the time the tooth remains outside the socket. Orthodontic treatment in patients with traumatized teeth is not contraindicated; however, clinical and radiographic aspects must be considered. Conclusion: Among the feasible orthodontic treatment options, the conservative approach can be a very favorable treatment alternative.

Bonded Retainers

Well-aligned anterior teeth are the major reason for the patients seeking orthodontic treatment, and keeping teeth aligned and stable afterwards is a goal for the orthodontist and the patient. Relapse after treatment is a common problem, and it is defined as when teeth go back to their previous positions. Removable or fixed retainers have been used to avoid relapse after treatment. It has been common practice to use removable retention to retain anterior teeth in the maxilla. However, in recent decades, it has become increasingly common to retain with bonded retainers. Almost all previous studies on retention devices in the maxilla were based on removable retainers. Consequently, there existed knowledge gaps and lack of short-term and long-term studies on the capability to maintain the stability of the maxillary anterior teeth with bonded retainers. Hence, the reason for the papers in this study. In addition, it is not known if retentionis needed in all orthodontic patients or if there are patients, based on their initial malocclusion and individual variations, who may not need retention after treatment. The research questions addressed in this thesis thus originate from knowledgegaps and clinical needs concerning retention strategies after orthodontic treatments. To provide strong clinical evidence, randomised controlled trials (RCT) as well as intention to treat (ITT) methodology has been assessed. The results are expected to be beneficial for the patients who will be offered the most effective retention strategy for maxillary anterior teeth based on patients’ preferences. In Paper I and II, 45 and 27 adolescents’ patients were collected from the Orthodontic Clinic in Mariestad, Sweden. At the time when Paper Iand II were conducted, there were no studies that had evaluated the longterm effect of bonded retainers in the maxilla. In two RCTs, Paper III and IV, 90 and 63 adolescents’ patients were collected from the Orthodontic Clinic in Växjö, Region Kronoberg, Sweden. Paper I: The aim was to investigate the amount and pattern of relapse of maxillary anterior teeth previously retained with a bonded retainer. Paper II: The aim was to investigate the amount and pattern of changes of maxillary anterior teeth seven years post-retention, which previously were retained with a bonded retainer. Paper III: The aim was to evaluate post-treatment changes in the irregularity of the maxillary six anterior teeth and single tooth Contact Point Discrepancy (CPD) of three different retention methods. Paper IV: The aim was to evaluate whether retention is needed after orthodontic treatment for impacted maxillary canines and with moderate pre-treatment irregularity in the maxilla. Key findings in Paper I • The contact relationship between the laterals and the centrals is the most unstable contact. Canines are the most stable teeth. • There was no difference in the relapse pattern between rotational displacements and labiolingual displacement. Key findings in Paper II • There was a strong correlation between irregularity at one- and seven-years post-retention. Stable cases one-year post-retention were stable and unstable cases deteriorated with time. Key findings in Paper III • All three retention methods showed equally effective retention capacity and all the changes found in the three groups were small and considered clinically insignificant. Thus, the null hypothesis was confirmed. All three methods can be recommended. Key findings in Paper IV • Changes between the retention and the non-retention group were statistically but not clinically significant. Since satisfactory clinical results one-year post-treatment were found in the non-retention group, retention does not appear always to be needed. • Most of the changes occur within the first 10-week period after treatment with no retention. Key conclusions and clinical implications Both removable and bonded retainers are effective for holding teeth inposition and can be used for preventing the relapse. It can be enough toretain with bonded retainer 12-22 instead of 13-23. It might be possibleto avoid retention in selected cases in the short-term, but a longer evaluationperiod is needed.

Complex Cases

The introduction of mini-implants has broadened the range of tooth movements possible by fixed appliance therapy alone. The limits of fixed orthodontic treatment have become more a matter of facial appearance than anchorage. Many complex cases which would previously have required surgery or functional appliances can now be treated with fixed appliance therapy using mini-implants. A mutilated dentition case where mini-implants were used to provide anchorage for intrusion of molars and retraction of anterior teeth is reported here to illustrate this point.

<p><strong><em>Background:</em></strong><em> One of the most common inflammation disease in the oral cavity for the past few years is the aggressive form of periodontitis. Common signs of aggressive periodontitis is the mobility of teeth especially in incisive and first molars, and occuring mostly in young patient. Young patients whose losing her anterior teeth, are a real challenge for dentist and prosthodontist. Prosthodontist need to consider both functional and esthetic aspects. <strong>Objective:</strong> Rehabilitation of young adult patient with aggressive periodontitis by an interdisciplinary approach of orthodontist and prosthodontist. <strong>Case Description:</strong> A young woman, suffered from aggressive periodontitis with major complain of her teeth mobility, especially incisive and first molar in mandible. She had undergone periodontal treatment, but the result was failed. The anterior teeth in mandible need to be extracted, therefore patient wished not to be in edentulous state. As preliminary treatment, we choose immediate denture to replace the anterior mandible teeth. We faced difficulties in mandible, because her right canine weren’t in the proper dental arch. So we asked orthodontist to place fixed orthodontics in mandible, to get the canine back in the proper arch. We’ve chosen orthodontic treatment,because we didn’t want to extract the canine teeth. We evaluated in six months and after the canine back in the proper arch, we proceed to long span bridge in mandible as our definitive treatment. <strong>Conclusion:</strong> By not extracting the canine teeth, we got some advantages, especially patient psychically was happier with her own teeth. The collaboration with another dentistry field, provides us better treatment for patient. After treatment, patient had no complaints and was happy with her new smile.</em></p><p><strong><em>Keywords:</em></strong><em>  Prosthodontic rehabilitation, aggressive periodontitis, orthodontic treatment, esthetic</em><em>.</em></p><strong><em>Correspondence:</em></strong><em> Chaterina Diyah Nanik.

Background The p64MW HPC and p48MW HPC flow diverters have reduced thrombogenicity due to hydrophilic coating. The purpose of this study was to evaluate its safety and efficacy in Mongolian patients under single antiplatelet therapy (SAPT) with prasugrel. Materials and methods We performed a retrospective review of patients enrolled into our prospectively maintained database to identify all patients treated with either the p48MW HPC or p64MW HPC under SAPT. We recorded baseline demographics, aneurysm size and location, procedural complications, angiographic and clinical results. Results 24 patients, (female = 21, 87.5%), age 48.2 ± 11.6 years (range 25–63) underwent treatment of 30 aneurysms with either p64MW HPC or p48MW HPC. All aneurysms were saccular with dome width 8.2 ± 6.5 (range 1.6–26.0 mm) and dome height 7.6 ± 6.7 (range 1.6–30.0 mm). None of the aneurysms were previously treated. The average PRU was 54.6 ± 31.2 (range 1–127) on pre-operative VerifyNow testing. Angiographic follow-up was available for 13 patients (17 aneurysms), 183 ± 36 days post-procedure, at which point 64.7% of aneurysms (n = 11/17) were completely occluded and 11.8% (n = 2/17) had only neck remnants resulting in 76.5% of aneurysms being adequately occluded A single intra-operative complication (4.2%) occurred however all patients were mRS ≤1 at last follow-up. There were two post-operative complications neither of which resulted in permanent neurological morbidity. There were no instances of post-operative aneurysmal rupture or delayed parenchymal haemorrhage. The overall mortality was 0%. Conclusion The efficacy and safety of p64MW HPC coated devices under SAPT is similar to uncoated flow diverters that require DAPT.

Abstract Backgroud To analyze the morphological changes of the anterior alveolar bone after the retraction of incisors in premolar extraction cases and the relationship between incisor retraction and remodeling of the alveolar base represented by points A and B displacements. Methods Pre- (T0) and post-treatment (T1) lateral cephalograms of 308 subjects in the maxilla and 154 subjects in the mandible who underwent the orthodontic treatment with extraction of 2 premolars in upper or lower arches were included. Alveolar bone width and height in both the maxillary and mandible incisor area were measured at T0 and T1 respectively. By superimposing the T0 and T1 cephalometric tracings, changes of points A and B, and the movement of the incisors were also measured. Then the correlation between incisor movement and the displacements of points A and B was analyzed. Results The alveolar bone width (ABW) showed a significant decrease in both maxilla and mandible (P < 0.001) except the labial side of the mandible (P > 0.05). The alveolar bone height (ABH) showed a significant increase in the labial side of maxilla and a significant decrease in the lingual side of maxilla and mandible. A strong positive correlation was verified between incisor movement and position changes of points A and B in both horizontal and vertical directions. Conclusions Anterior alveolar bone width and height generally decreased after orthodontic treatment. Incisor retraction led to significant position changes of points A and B. The decrease of anterior alveolar bone due to significant incisor retraction should be taken into account in treatment planning.

Abstract This case report describes an esthetic treatment to improve the shape and alignment of the anterior teeth, reestablishing smile harmony, using feldspathic porcelain veneers. Results of clinical follow up after 36 months are also presented. The advantages, disadvantages and limitations of the technique are detailed with reference to the relevant literature. This suggests that the success of treatment depends on adequate conditions of bonding between the veneers and the tooth complex, which involves parameters such as the strength and durability of the bond interface. Therefore, the clinical success of feldspathic porcelain veneers depends on the accurate selection of cases and correct execution of clinical and laboratory procedures. The rehabilitation involved from first right premolar to the left with feldspathic porcelain veneers made on refractory dies. After the 3-year follow up, excellent clinical results and patient satisfaction were achieved.

Bonded Retainers

The lower fixed retainer from cuspid to cuspid has been one of the commonly used methods of retention at the end of the orthodontic treatment. Orthodontists mostly use the lingual wire soldered to cuspid bands for the fixed lower retainer. With the advent of the new effective bonding materials many orthodontists prefer to use cuspid-to-cuspid/biscuspid-to-biscuspid bonded retainers to obtain optimal retention of lower anterior teeth both functionally and aesthetically. After experimenting with a variety of previous methods, such as the use of rubber bands, elastic threads, cotton pliers, ligature wires and silastic trays for the accurate placement and immobilization of a lower lingual retainer during the bonding, we have found that the use of two 1 to 1½ inch pieces of 0·016 inch wires tack welded to lingual wire gives the best results. It is more accurate, simple, inexpensive and designed to save the orthodontist chair time.
